About Your eXact®Eco-Check Instrument
In order to save power, the meter is designed to turn off after 3 minutes (timed
from the last button pressed).
Should the meter turn off in the middle of a test, the last stored zero in the meter
will remain valid when the meter is turned on again. Also, the test result is stored
in memory for easy retrieval.
The eXact
®
Eco-Check meter is controlled by three buttons:
1. ZERO/ON:KHQ¿UVWSUHVVHGWKLVEXWWRQWXUQVWKHPHWHURQ:KHQWKH
meter is on and this button is pressed, it zeroes the sample in the cell. Once the
meter is zeroed, this zero value applies to all parameters and is stored and
retained even when meter turns off. However, it is recommended that each new
water sample analyzed is zeroed before testing, to maximize sensitivity and
accuracy.
2. MENU: With each press, the MENU button advances through the tests in the
following sequence: AL1, NO2, NO3, NH4, TH5, CL6, bt7, PO8, CU9, CH0, P11.
Each test menu can store up to 20 results. To retrieve the stored results, go to
the desired test using the MENU key. When the desired test is displayed, press
and hold down the MENU key. Continue holding down the MENU key to scroll
the stored results for that test, starting with the most recent result. The meter will
display, from memory, the last 20 readings in sequence beginning with -20, which
is the latest result, followed by -19, which is the 2
nd
ODWHVWUHVXOWHWFDQG¿QDOO\
-01, which is the oldest result retained. Only the last 20 readings are stored in
each menu. This meter is able to store 220 results in memory (20 in each menu).
3. READ: When pressed once, this button starts the timer for the parameter
being tested and proceeds for each test procedure. When pressed a second time
the meter exits the timer and immediately prepares to colorimetrically measure the
sample (not accurate, for accurate results you need to wait the entire reaction
time) and simultaneously stores the measurement in memory.
If the parameter being measured is below or above the detection range, the display
will show “LO” (Under Range) or “HI” (Over Range), respectively. This feature is

Mini Dilution Kit II (487202) Instructions
Free Chlorine (DPD-1) Test Procedure
Kit includes: Graduated Cylinder (50mL) with cap; Graduated 3mL Syringe
(labeled at 0.1mL increments).
How to do 1 to 20 dilution using the 3mL syringe (dilution factor of 20)
Rinse the 3mL syringe three times with water sample that you are about to test.
1. Rinse the 50mL graduated cylinder three times with distilled or deionized (salt free) water.
2. Fill the 3mL syringe to the 2mL line by pulling up water sample to be tested with upward motion
of plunger to the 2mL line. Note that the plunger ring should line up at the 2mL line.
3. Hold the filled syringe over a clean 50mL cylinder. Push the plunger all the way down to add
the sample to the cylinder.
4. After adding sample to the cylinder, fill the graduated cylinder to the 40mL line with distilled or
deionized (salt free) water. Securely put the cap on the cylinder.
5. Mix the contents of the graduated cylinder by turning the cylinder up side down at least three
times. The sample is ready to add to the meter for testing.
Other dilutions possible with the 3mL syringe are as follows:
Volume in syringe Volume filled in Cylinder Dilution Factor
1.0mL 40mL 40
1.0mL 30mL 30
1.0mL 20mL 20
0.5mL 50mL 100
0.5mL 25mL 50
0.2mL 50mL 250
CALCULATION:
Test Result x Dilution Factor =
Actual Result
NOTE: Chlorine reacts with N,N-diethyl-p-phenylenediamine as it is released from the strip to form a magenta color,
directly proportional to the Chlorine concentration.
DO NOT discard the sample from the Free Chlorine test if you are planning to run eXact®
Strip Micro DPD-3 (Combined Chlorine) Procedure. Move directly to steps 7-9 on page 16.
Otherwise, rinse the cell immediately.
*NOTE: When testing outdoors (sunlight), for best accuracy, use the Mixing Cap/Cell Cover when Zeroing and Reading the sample.

with DPD-3 will, in the presence of Combined Chlorine or Chloramines, convert into Iodine).
DIP STRIP AND PRESS “READ”
*NOTE: Standard Method (4500-Cl G, procedure for total chlorine) requires the reading to
be made after 2 minutes from the time the KI is added. For compliance testing, you must
time the two minutes and then make your measurement. NOTE: From testing in our lab,
water samples above 70°F (20°C), generally, reach a stabilized reading quicker then 2 minutes.

Color similar to free chlorine reaction at all levels.
Color development is reduced above 10 ppm (mg/L).
Color similar to free chlorine reaction at all levels.
See AWWA procedure 4500-CL F, 1(d) for removal of interferences.
Monochloramine interferences are known to occur in free chlorine
DPD methods. This interference is dependent on temperature and
monochloramine concentration.
Color similar to free chlorine reaction at all levels.
Interference is possible.
Typical pH samples of potable water with a pH of 6.0 to 9.0 are
OK. If outside this range adjust to pH 6.0 to 7.0 using acid
(0.5 N Sulfuric acid) or base (0.5N Sodium hydroxide).

CL6: Chlorine and Iodine react with N,N-diethyl-p-phenylenediamine as it is released from the strip to
form a magenta color, directly proportional to the Chlorine concentration. (Ozone, Bromine, and

eXact®Eco-Check Tips For Best Accuracy
Become familiar with the meter and the different tests by reading the instructions
carefully.
The Free Chlorine and Total Chlorine results are compliant for meeting USEPA
(4500-Cl G); ISO 7393/2; and German DIN 38408 G4-2 requirements.
Observe the dip time (as required for the test) for accurate results.
7HVWLPPHGLDWHO\DIWHU¿OOLQJWKHCELL with water sample.
Be sure the CELL LV¿OOHGWRFDSDFLW\P/
Rinse the CELL with clean water immediately after completing the test. (Some test
reagents will stain or coat the CELL wall if allowed to remain).
Just before testing, rinse the sample CELL with the sample water several times to get a
representative sample. (Use deionized or distilled water for rinsing if you have a limited
sample).
Store the meter and all test materials out of direct sunlight and away from chemical
storage areas.
Minimize exposure of meter and test reagents to heat above 90°F (32°C).
Dry the outside of the meter when testing is complete or before storage of the meter.
Each eXact®Strip Micro test strip is valid for ONLY one test. Discard strip after single
use in regular trash that is inaccessible to children and pets.
Each bottle of eXact®Strip Micro contains the quantity of strips notated on the bottle.

normal strips in the bottle. These should be discarded. Using these strips may give
unreliable results.
The eXact®Eco-Check meter is not compatible for use with DPD-1, DPD-3, and DPD-4
powder pillows, tablets, and liquids available from other manufacturers. Accurate
results can only be guaranteed by using genuine eXact®Strip Micro strips or reagents
(reorder information on page 19).
Our lab testing with the Micro 20 meter has shown that zeroing and measuring of the
sample normally does not require any cell cover for accurate results, except in sunlight.
To obtain optimal accuracy when testing with the meter outdoors (sunlight), use the
Mixing Cap/Cell Cover when zeroing and reading the sample.
Remove batteries when meter is not used for more than a month (Warranty
Requirement).
If there is a question about the quality of a ReagentStrip

using the appropriate READY SNAP
