This manual uses symbols defined below to indicate cautions and
notes that promote the safe and correct use of this product.
The Caution symbol indicates that failure to observe this
instruction can result in injury to the operator or damage to the
product or property.
N
The Notes symbol indicates operational tips for correct use of
the product to prevent problems and/or errors with the products or
its interpretation.
CAUTIONS:
1. With a detector tube inserted and the handle drawn back,
the pump cylinder is under a high vacuum. If the handle lock is
released under vacuum conditions, it will pull back suddenly.
Holding the pump by the extended shaft can lead to injury. Always
hold the pump by the cylinder, never by the shaft.
2. Broken glass tube tips can fall from the tip cutter or storage area
when using the pump. To prevent glass contamination in restricted
areas (e.g., food processing plants) use the optional Nextteq Tip
Cutter with Container NX90153.
3. Normal use of detector tubes requires the handling of broken
glass tubes. Safety glasses and protective gloves are recommended.
4. Detector tubes contain small amounts of chemical reagents,
which may be toxic. Avoid skin and eye contact with the internal
chemical reagents.
5. If the reagent is completely discolored (i.e., the detector tube
is over – ranged) after measuring a high concentration toxic gas
(e.g., a process measurement), the possibility exists for harmful gas
residue to remain inside the pump cylinder. This gas will exhaust
from the back of the pump cylinder when the handle is pulled out
for the next pump stroke. Whenever the tube has fully discolored,
purge the air inside the cylinder by pulling and pushing the handle
several times in a well-ventilated area.
6. Keep detector tubes out of the reach of children. If they are
used in schools, teachers or parents should be responsible for safe
operation.
7. The NX-1000 Sampling Pump with Automatic Stoke Counter is
NOT intrinsically safe and is NOT to be used in hazardous areas
where there is an explosion potential.
N
NOTES:
1. All Nextteq Gas Detector Tubes are wrapped in a thin
transparent film that protects against the shattering of the glass
tube. However, since they are made of glass and may break, we
recommend wearing protective goggles and protective gloves to
prevent injuries.
2. Do not direct the tip of a detector tube toward a person when it
is attached to a sampling pump (when inspecting for air-tightness
or during measurement). Otherwise you may injure the person
with the tube end.
3. When using a sampling tube, be sure to hold the cylinder and
the handle, not just the shaft. If the handle lock is released when
inspecting air-tightness or when sampling gas, the handle may
suddenly snap to its original position, pinching or injuring your
fingers.
4. When breaking off the tip of a detector tube, never grasp the
tube strongly. Otherwise the detector tube may break and you may
injure yourself.
5. If you break the detector tube, do not pick up the broken
pieces of the detector tube or touch the detecting reagents with
your bare hands. Otherwise you may injure yourself. If detecting
reagents come in contact with the skin, immediately rinse the area
with water. Sweep away any broken pieces of glass or detecting
reagent(s), then wipe the swept area with a damp cloth.
6. To prevent broken pieces of glass or detecting reagents from
injuring your eyes, be sure to keep the detector tube away from
your eyes when breaking off its tip. If you do get a piece of glass
or detecting reagent in your eyes, do not rub your eyes with your
hands. Immediately rinse your eyes with plenty of water and see
a doctor.
7. The ends of the detector tubes with their tips snapped off may
cause injuries. We strongly recommend covering the ends with
rubber caps.
8. When removing the detector tube from the sampling pump,
hold the tube firmly at a point close to the attachment and pull it
straight out. Never bend the tube or strongly grasp it. Otherwise
you may break the tube and injure yourself.

9. Choose detector tubes carefully using the tube selection
guide and pay strict attention to chemical names and measuring
ranges. If the proper detector tube for a particular application is not
chosen, a correct reading cannot be obtained.
10. When gases other than the target gas are also suspected, refer
to the tube instructions for information on interfering compounds
and to the handbook for information on other relevant detector
tubes.
11. A detector tube is designed for a single use; do not re-use
detector tubes.
12. A detector tube should be used immediately after breaking
the ends. Detector tubes exposed to the air for a long time after
breaking the ends will give erroneous readings, and may not
respond to the target gas at all.
13. Read the concentration immediately after completion of
measurement. If not read immediately, the stain may lengthen or
fade, which can lead to erroneous readings. It may be useful to
photograph the detector tube immediately after sample completion
to document the result.
14. A leaking pump will produce low readings. Always check
the pump for leakage before use in accordance with the section
“Operating Procedures – Leak Test.”
15. The temperature range for use of detector tubes generally
is 0 to 40˚C. Use detector tubes only in the temperature ranges
specified on the Nextteq Detector Tube Box or the Instruction
Sheet inside the Nextteq Detector Tube Box. Temperature ranges
are also listed in the Nextteq Gas Detector Tube and Pump System
Handbook. When using detector tubes at temperatures outside of
the above range, refer to the section “Reading the Nextteq Detector
Tube – Conditions that affect results and how to correct.” Use
sampling pumps only in temperatures ranging from 0˚C to 40˚C
(32˚F to 104˚F). Using the sampling pumps and detector tubes
outside their respective operating temperature ranges may cause
the pumps to leak or result in erroneous measurements.
16. Do not drop or strike the pump. If the cylinder is dented, it will
impede the handle operation and possibly cause leakage.
17. Should the pump be disassembled, only hand tighten on
re-assembly. Over-tightening can damage threads.
18. Clean the pump only with a dry paper towel. Do not use water
or solvents.
19. Do not store the pump in areas of high temperature or high
humidity. Do not store with the handle extended, as the pump shaft
is susceptible to bending under stress.
20. It is recommended that service repair be done only by
authorized service centers. Any service or repair must be followed
by a leak check prior to field use.
21. Note that the NX-1000 pump is a vacuum pump only, and it
cannot be used for specialized detector tubes that require sample
entry by pressure or injection (Oxygen, Hydrogen, Propane, etc.).
22. If using the following detector tubes, it is necessary to
purchase and use the flow control orifice option.
Acetylene and Ethylene – Tube Number NX105
(two tube measurement)
Phosphine in Acetylene – Tube Number NX204SH
Phosphine in Acetylene – Tube Number NX204SM
Carbon Monoxide in Blood – Tube Number NX711
Ethyl Alcohol in Blood – Tube Number NX712
Hydrogen Cyanide Blood – Tube Number NX713
Hydrogen Sulfide Blood – Tube Number NX714
23. The following conditions apply to special Nextteq
Detector Tubes:
• Nextteq TWA detector tubes and some specialty detector
tubes require a continuous flow sampling pump. Nextteq’s
NX-300, NX-1200 or NX-5000 meet the required flow
rates for these applications.
• Airteq tubes for compressed breathing air analysis do
not require sampling pumps but require the use of a
regulator. Nextteq’s Deluxe Airteq Kit comes complete with
a regulator and the required Nextteq Airteq detector tubes.
• Solution tubes do not require sampling pumps.
Please see the Nextteq Gas Detector Tube System Handbook or the
Nextteq Gas Detector Tube Guide for complete tube listing with the
required equipment to be used for sampling.

including: Industrial, Manufacturing, Chemical, Energy,
Construction, Transportation, Medical, HAZMAT, Uniformed
Services and Government Agencies. Simply put, Nextteq’s Gas
Detector Tube and Pump System is designed, built and supported
by industry professionals for industry professionals.
The Nextteq Detector Tubes: Nextteq’s pre-calibrated detector
tubes are the direct-read type with a single calibration scale
printed on each tube; measurement is as simple as reading a
thermometer. Each detector tube is wrapped in a thin transparent
film that protects against the glass tube shattering and the release
of the chemical reagent in the event of accidental tube breakage.
The unique absorbing media provides stable, long-term shelf life,
and high resolution. The tubes’ distinct lines of demarcation make
quantitative results easy to see and reduce measuring errors. Each
production lot of tubes undergoes strict quality control and testing
to ensure the highest level of performance and quality.
The Nextteq Gas Sampling Pump: The Nextteq NX-1000 Gas
Sampling Pump can precisely collect the required sample volume
for a detector tube inserted in the pump. The sample concentration
of the gas or vapor being detected can be read right on location
– a grab sample. The red lines on the pump shaft mark exactly
when the handle is at the full-stroke (100 mL) and the half stroke
(50 mL) positions. When sampling, the handle will click and
will be precisely locked at those positions. If you pull the pump
handle back fully “n” times (allowing for a sampling time interval
between each pump stroke), a total volume of (100 mL) x “n” can
be sampled. For example:
Each detector tube is calibrated based upon a prescribed
(standard) volume of sample. You can obtain accurate gas or
vapor measurements in minutes.
Each pump piston has been designed with a smaller diameter
contoured grip so that the handle can be pulled back with even
less effort. There is no power supply or batteries required. The
Nextteq NX-1000 Gas Sampling Pump’s lightweight non-sparking
design provides you with advanced superior features including an
antibacterial nonskid grip, intrinsically safe design, a hand strap,
and a convenient compact size easily carried for field use.

NOTE: If there is a leak in the sampling pump you cannot
obtain the correct measurement values, e.g. measured values may
be lower than the actual values or there may be no response at all.
Be sure to check the sampling pump for air-tightness before doing
any measurements and check the operation of the flow finish
indicator at this time.
A. Leak Test - Inspecting the air-tightness of the
sampling pump PRIOR TO USE:
1. Confirm the inlet clamping nut is firmly tightened.
2. Confirm the pump handle is fully in, then insert a sealed,
unbroken detector tube into the rubber tube inlet. At this time,
make sure the flow finish indicator is popped out.
3. Align the red line on the bottom case and that of shaft.
Securely hold the cylinder of the sampling pump. Then pull out
the handle fully along the red guideline on the pump shaft to full
stroke locked position. Wait one minute.
4. Unlock the handle by turning it ¼ turn (90 degrees), and check
to see if the handle returns to the initial position. Also confirm
the flow finish indicator has been popped out again. When the
lock is released under full vacuum, the handle tends to snap back
quickly. To prevent possible damage to the locking device allow
the handle to return slowly by holding the cylinder and handle
securely. If the handle returns completely to the original position
and the flow finish indicator has popped out, then the performance
is satisfactory.
CAUTION: HANDLE
WILL TEND TO SNAP
BACK INTO THE PUMP
QUICKLY.
When the handle is
unlocked, be sure to
guide it back gradually by
applying a little resistance.
Otherwise the handle will spring back due to the vacuum in the
pump cylinder and possibly damage internal parts or cause injury.
To correct a leaking pump, consult “Section 12: Maintenance”
to ensure pump is greased properly.
A functional failure in the finish indicator may lead to a leak.
If a failure is found in the indicator, immediately contact your
local authorized Nextteq Distributor to repair it or call Nextteq
to obtain an RMA for repair.

B. Selecting the Nextteq Detector Tube
Nextteq precision gas detector tubes vary in type according to the
gas or vapor to be detected and the required detection range. They
are used for measuring gases or vapors in different concentration
ranges. As gas or vapor concentrations can vary from high to low,
and Nextteq gas detector tubes vary in detectable concentrations
from high to low, please refer to Nextteq Gas Detector Tube and
Pump System Handbook for the complete offering and in-depth
description of all Nextteq Detector Tubes.
Figure 4: Nextteq Gas Detector Tube and Pump System Handbook
P/N NX90118-001
Nextteq gas detector tubes are of two basic types:
1) Length of stain detector tubes
A) Direct Reading tubes:
• Single tube and
• Twin and Triplet tubes that utilize a pre-treat tube(s)
or post-treat tube
B) Concentration Chart tubes
2) Color Chart tubes
It is important to take time to select the Nextteq detector tube
most appropriate for your target substance and presumed
concentrations. If you need assistance, please call your Authorized
Nextteq Distributor or Nextteq customer service.
Confirm the standard number of pump strokes (n) and the
sampling time for the tube, and the connection sequence if a twin
tube or triplet tube is selected.
Check if the detector tube requires correction for temperature,
humidity, atmospheric pressure, or interfering gases to the tube
reading. Consult “Section 10: Reading the Nextteq Detector Tube –
Conditions that affect results and how to correct.”
N
NOTES:
1. Be sure to use only Nextteq Gas Detector Tubes with the Nextteq
NX-1000 Gas Sampling Pump. If you mix manufacturer Tubes and
Pumps you may end up with erroneous measurements.
2. Use a Nextteq Detector Tube that has been stored under
its specified storage conditions indicated on each Nextteq
Detector Tube Box. If your detector tubes are not stored in their
specified storage conditions, you may end up with erroneous
measurements.
3. When the temperature of the detector tube itself differs from that
of the measurement environment, first assimilate the detector tube
temperature to the ambient temperature; otherwise you may end
up with erroneous measurements. For a tube that has been stored
in a refrigerated environment, leave tube for about 15 minutes in
the measurement environment to assimilate its temperature to the
ambient temperature.
4. Do not use a detector tube in which its “expiration date” has
expired. Otherwise, you may end up with erroneous
measurements.
5. Break off both ends of the detector tube immediately before the
measurement. Using a detector tube that has been left with its tips
broken off may result in an erroneous measurement.
6. Read the concentration immediately after completion of
measurement. If not read immediately, the stain may lengthen or
fade, which can lead to erroneous readings. It may be useful to
photograph the detector tube immediately after sample completion
to document the result.
CAUTION: Never re-use a detector tube.

D. Taking a Sample
N
NOTES: prior to sampling:
1. The operating procedure varies from one Nextteq detector
tube to another. Before proceeding, carefully read the individual
instruction sheets provided in each box.
2. Some Nextteq detector tubes require temperature correction
using tables provided in the instruction sheets. Be sure that the
tube temperature has reached equilibrium with the sample area
before drawing the sample. Note the temperature on the Thermal
Ring prior to sampling.
3. When using Nextteq detector tubes at a pressure other
than normal atmospheric pressure, correction of the reading
is necessary. Refer to the Section 10 B –“Reading the Nextteq
Detector Tube – Conditions that affect results and how to correct.”
To read the tube scale directly, it is necessary that the pressure of
the sample gas is equal to that of the aspirating pump.
4. When sampling high-pressure systems, or areas where the
NX-1000 cannot be used, first collect the sample in a Nextteq
VeriAir Flex Self-Inflating Sample Bag. Bags are available in foil
or Tedlar depending upon your application. Then, you can use the
NX-1000 pump to draw the sample from the bag. Nextteq offers a
complete line of VeriAir Flex Sampling Bags. Consult Nextteq in
selecting the correct VeriAir Sampling Bag for your application.
D. Taking a Sample (continued)
1. Prepare NX-1000 Sampling pump.
Check the pump for leaks in accordance with “Section 9A:
Operating Procedures – Leak Test”
2. Break off both ends (tips) of the gas detector tube.
Insert the tip of the Nextteq gas detector tube into the tip cutter
on the NX-1000 Sampling Pump and scratch the tip of tube by
rotating it for one revolution, then pull it toward you. (The glass
tips can be thrown away by removing the tip cutter cap.) An
optional accessory, the Nextteq Tube Tip Cutter with container
P/N NX90153 is available. It is a transparent container to let
you see the amount of fragments. It holds 200 broken tips and
is reusable.
SECTION 9
STEP 1:
Rapidly collect a whole air

3. Connect the gas detector tube to the aspirating pump.
Confirm the pump handle on the NX-1000 is fully pushed in and
the bottom red line on the pump shaft cannot be seen. The sample
gas must be drawn through the Nextteq gas detector tube in the
correct direction. Insert the Nextteq gas detector tube into the
rubber tube inlet with the tube’s directional arrow pointing toward
the pump.
4. Pull the handle.
Align either red line on the shaft to either red line on the bottom
case and pull the pump handle to its full 100 mL locking position.
If the sample calls for a half stroke, pull out the pump handle until
50 mL line appears, and shaft will be locked at 50 mL. All Nextteq
tubes will indicate the volume of air (e.g. 100 mL) directly on the
tube for the standard measuring range printed on the tube. Check
the Nextteq Tube Guide, Nextteq Handbook, Nextteq Detector Tube
Box or the tube Instruction Sheet for alternate extended ranges and
pump strokes.
5. Draw the sample gas.
Direct the detector tube end to the point of measurement. Draw the
sample gas for the specified time at the desired sampling point.
For 100 mL sample pull out the handle fully and for the 50 mL
sample pull out the handle halfway along the guide. Confirm with
the flow indicator that the sample is completed. The estimated
sample time required for each detector tube is stated clearly in the
instruction sheet.
6. Return the handle.
When the sample is completed, turn the handle ¼ turn (90
degrees) clockwise or counterclockwise to unlock the handle.
Confirm that the handle remains extended. (If the handle returns
part way, the sample is incomplete, and this will cause a low
reading). Some detector tubes require extra pump strokes (i.e.,
more than 100 mL of air). In this case, push the handle back and
repeat the operation.
7. Read the concentration.
Remove the gas detector tube from the Nextteq Sampling Pump
after the prescribed sample volume has been drawn. Read the
concentration of gas at the maximum end of the stain against the
printed scale on the detector tube. It may be useful to photograph
the detector tube immediately after sample completion to
document the result. Some detector tubes require a temperature
correction using a table or correction coefficient provided in the
instructions.
N
NOTE: Remember to remove broken glass tips in the pump
head block before it becomes full. Remove the entire red tip cutter
cap and shake out the broken glass tips and carefully dispose of
them. After disposing of the broken glass tips, securely re-insert
the red cap.

Section 10: Reading the
Nextteq Detector Tube
A. How to Read the Scale:
All Nextteq Detector Tubes are of the following types when
determining the gas concentration:
1) Length of Stain detector tubes
A) Direct Reading tubes:
• Single tube and
• Twin and Triplet tubes that utilize a pre-treat
tube(s) or post-treat tube
B) Concentration Chart tubes
2) Color Chart tubes
For Length of Stain - Direct Reading Tubes:
Read the concentration of gas at the maximum end of the stain
against the printed scale on the detector tube.
For Length of Stain - Concentration Chart Tubes:
Nextteq Concentration Chart Tubes utilize a printed chart
used to determine the concentration of the gas or vapor preset.
After completing the sample,
align the zero end of the
detecting reagent (inlet side
of the tube) with the 0 – 0
line on the concentration
chart. Align the other end of
the same layer (exit side or
pump side of the tube) with
the X – X line respectively.
Read the gas concentration
at the maximum end of the
stain against the scale on the
card. If the end is slanted,
read at the middle point of the
oblique stain.
For Color Chart Tubes:
There are two types of Color Chart Tubes:
1) Tubes that have several sections of specific reagent that will
change color to identify the type of gas present. For example,
Inorganic (NX301) and Organic (NX302) qualitative detector
tubes have a special color chart to identify 60 chemicals in a
couple of minutes.
2) Tubes whose reagent sections will show a change in color
intensity proportional to the concentration of the target gas which
can be measured by comparing the tube’s color stain to a color
intensity chart. For example, with Carbon Monoxide (NX119SA
and NX119SB), the color goes from pale yellow to green to blue
depending on the concentration of CO and other gases present.
READING ONE
In case the end of the
stain is slanted:
Read out the numerical
value at the middle of
the oblique layer.

In case of faint
discoloration:
Read the concentration
of the gas at the
maximum end of
the stain.

B. Conditions that Affect Results and How to Correct:
Sample Volume:
Graduations on the detector tube showing the concentration of gas
are generally calibrated to 100 mL (100 cc), the quantity of gas
passed through the detector tube in one complete pump stroke of
the Nextteq NX-1000 Gas Sampling Pump. Some detector tube
graduations are calibrated to 200 mL or 300 mL (two or three
complete pump strokes). The term pump “stroke” simply means
the number of times the sample pump is operated (pump handle
pulled back all the way and allowed to automatically lock). The
discolored layer generally lengthens in proportion to the quantity
of gas passed through the detector tube. When a gas or vapor is
present in concentrations lower than the lowest graduation on the
detector tube, the approximate concentration value can be found
by increasing the sample volume to several hundred milliliters
(several pump strokes) and dividing the concentration value read
on the detector tube by the number of pump strokes. It should
be noted, however, that the quantity of gas or vapor detected may
not be exactly proportional to the length of the discolored layer
obtained due to the effects of moisture and a depleted oxidizer.
Temperature:
The temperature of the gas detector tube (normally the same
temperature as the sampling environment) can also affect the
measured concentration of gas or vapor for the following reasons:
• An increase or decrease in the sample density
caused by a temperature change.
• A change in the quantity of gas or vapor reacting
with the detecting reagent.
• A change in the rate in which the detecting reagent
reacts with the gas or vapor.
These effects can overlap one another, causing the length of the
stain in the detector tube to increase or decrease. Or they can
offset one another, having no effect on the measured value. Those
Nextteq gas detector tubes that can be affected by temperature
changes are provided with a temperature correction table as part of
the instruction sheet packed with each box of detector tubes.
Temperature Correction Procedure:
1. In Case of Use of Correction Table
[EX.1] When the tube reading is 550 ppm at 25˚C, the
true concentration is found by interpolating between the
concentrations listed for 20 and 30˚C. in this example, the
corrected value is 560 ppm.
2. In Case of Use of Correction Coefficient
[EX.2] When the detector tube is reading 0.4mg/l at 23˚C, the
true concentration of water vapor is 0.36 mg/l by the following
calculation.
0.4 mg/l X 0.90 = 0.36 mg/l

Humidity:
While nearly all Nextteq gas detector tubes are not affected by
unsaturated water vapor, some detector tubes are formulated with
• Both a dehumidifying reagent and detection reagent
together in the tube, or
• A separate dehumidifying tube that is connected to
the detector tube with a connector supplied in each
box of tubes.
However, water droplets can enter a detector tube; water can even
condense inside the detector tube due to temperature changes.
Both of these situations can have a serious effect on both the
gas or vapor readings obtained and the actual color change of
the detector tube. For these reasons, taking readings with the
Nextteq Water Vapor tubes prior to gas or vapor sampling is
recommended.
Coexisting Gases or Vapors:
While the detecting reagents in Nextteq gas detector tubes are
formulated to react uniquely with the gas or vapor to be measured,
they can also show a similar reaction (color change) with another
gas or gases having similar chemical properties. It is necessary to
carefully consider this when taking gas or vapor readings with any
gas detector tube.
A coexisting gas or vapor can have the following effects on gas
detector tubes:
• It may not discolor the detecting reagent, but can give
a higher or lower reading.
• It can discolor the detecting reagent in a similar way,
giving a higher reading than the actual concentration.
• It can give an entirely different color change in the tube.
• It can give the discolored length with an indistinct
end point.
Atmospheric Pressure:
Tube readings are affected by significant fluctuations in
atmospheric pressure. All Nextteq detector tubes are calibrated
based on a standard atmospheric pressure of 1 atmosphere (760
mmHg, 1013 hPa) and readings will not be affected at pressure
fluctuations of ± 10%. If the pressure at the time of measurement
is not within this range, correct the tube readings as follows:
Actual concentration =
Tube reading x
Or
Tube reading x
Or
Tube reading x
Shelf Life:
Gas detector tubes use chemical reagents that inevitably
deteriorate over time. Because of this, if detector tubes are used
after the stated shelf life expiration date (stamped on each box of
tubes), they may not show an accurate gas or vapor concentration.
While the highest purity reagents are used in formulating Nextteq
detector tubes to ensure the longest shelf life possible, complex
chemistries used to detect some gases and vapors make it
important to use tubes before the stamped expiration date.
Storage:
All Nextteq detector tubes should be stored in a cool, dry, and
dark place and out of direct sunlight to ensure adequate shelf life.
All Nextteq tube boxes will indicate one of the following storage
conditions:
1. “Store in a cool, dry, and dark place at 32-77˚F
(0-25˚C) for tubes that do not need to be refrigerated,
but can be refrigerated.”
2. “Store in a refrigerated place at 32-50˚F (0-10˚C)
for tubes that do need to be refrigerated.”
3. “Store in a cool, dry, and dark NOT REFRIGERATED,
at 68-77˚F (20-25˚C).”
Detector tubes improperly stored inconsistent with the storage
condition stated on the front of each detector tube box or in direct
sunlight may show a performance deterioration even if they are
within the stated shelf life.

Section 11: Disposal of Nextteq
Detector Tubes
Detector tubes contain a chemical reagent which reacts with the
target gas. The chemical reagents used vary among different types
of detector tubes, and may include substances regulated by laws for
proper disposal. When discarding used or expired detector tubes,
always dispose of them properly in accordance with your local
regulations. For further information contact your local distributor or
the manufacturer’s head office or branches.
Section 12: Maintenance
Application of New Vacuum Grease
1. Pull the handle part way and turn the bottom case
counterclockwise to remove it.
2. Pull the piston out from the cylinder.
3. Wipe off the old grease and dirt from the piston and inside
the cylinder using a clean paper towel. Apply a thin coat of
vacuum grease to the rubber gasket of the piston. When
wiping off the old grease, be careful not to scratch the
inside walls of the cylinder. Reassemble pump.
Replacement of Rubber Tube Inlet and Rubber Tube

5 and 10 Meter
Extension Hoses:
The convenient 5 and
10-meter hose design
eliminates the need for you
to factor in hose line air
volume when sampling.
Sample results can be read directly from the detector tube; no
additional calculations, charts or correction factors are required.
20-Meter Extension Hoses:
The 20-Meter Extension Hose comes in two configurations: One
with a tube holder for single tube applications (P/N NX90148)
and one with a tube holder for dual tube applications (P/N
NX90149). Designed to satisfy demand for efficient and complete
sampling of a ship’s large cargo holds, stack sampling and
other deep confined spaces. The 20-meter hose is identical in
materials, construction and method of assembly as the 5 and
10-meter hoses. Due to the long length of the 20-Meter Extension
Hose, there is increased flow resistance causing a reduction in the
vacuum which effects the length of stain. Therefore, some tubes
need a correction factor and/or longer than normal sampling time
to account for the reduced vacuum.
