Introduction
GAS-Mate is an intrinsically safe instrument designed to detect leaks of a variety
of combustible gases and flammable refrigerants. It can be used for many leak
testing applications including, but not limited to:
Combustion appliances
Gas-fired furnaces
Gas stoves
Hydrocarbon-based (flammable) refrigerants
Gas pipelines, valves and meters
Heat exchanger testing with combustible gases
GAS-Mate is sensitive to a variety of hydrocarbons and other gases including, but
not limited to:
Natural Gas
Cyclopentane
Isobutane (R600a)
Methane
Propane (R290)
Ethane
Butane
Ammonia
Ethanol
Hydrogen Forming Gas (95/5)
NOTE: GAS-Mate does NOT detect carbon monoxide (CO).

Product Warnings
WARNING
To prevent ignition of a hazardous atmosphere, batteries must only
be changed in an area known to be nonhazardous (i.e., completely
free of combustible gas).
WARNING
Use only Duracell® MN1300 batteries to maintain intrinsically safe
approval.
WARNING
Always check instrument operation with a known combustible leak
source before use.
WARNING
GAS-Mate will detect leaks as described below but may not indicate
when a hazardous atmosphere is present due to its Auto Zeroing
function. Lack of a reading by GAS-Mate should not be taken as an
indication that the atmosphere is totally safe.
WARNING
There are no user serviceable parts inside. Do not disassemble
GAS-Mate.

Install Two “D” Cell Alkaline Batteries
WARNING
To prevent ignition of a hazardous atmosphere, batteries must only
be changed in an area known to be non-hazardous (i.e., free of
combustible gas).
CAUTION
Use only Duracell® MN1300 “D” size batteries to maintain
intrinsically safe approval.
1. Remove the battery cover by releasing the latch and sliding the cover down and
off the handle. You may need a small flat-blade screwdriver to assist with
releasing the latch.
2. Install two Duracell® MN1300 “D” size alkaline batteries as shown in Figure 1.
Figure 1 Properly installed alkaline batteries
3. Reinstall the battery cover by aligning it in the grooves on the handle and sliding
it up the handle until it latches.
NOTE: If the Battery indicator flashes or if the Battery and highest signal indicator
both flash, the batteries are low and should be replaced.
NOTE: Dispose of depleted alkaline batteries according to applicable state and
local regulations. In the absence of such regulations, recycle and/or
dispose of batteries through voluntary waste recycling programs.

Using GAS-Mate
1. Long press the Power button to turn GAS-Mate On or Off.
NOTE: GAS-Mate should be turned on in clean air free of combustible gas.
2. Wait for GAS-Mate to warm up, about 30 seconds up to two minutes.
NOTE: GAS-Mate will alarm during warm-up and the highest leak indicator
will illuminate. When warm-up is complete, GAS-Mate will beep
steadily.
3. If needed, adjust sensitivity by swiping up or down on the touch pad. The leak
indicators will illuminate to indicate the sensitivity level.
NOTE: GAS-Mate defaults to maximum sensitivity on startup. It is
recommended to use this setting for most applications.
4. Carry GAS-Mate into the area of the suspected leak. An alarm at this time
indicates a build-up of combustible gas in the general area.
NOTE: When GAS-Mate detects combustible gas, it will alarm and the leak
indicators will illuminate. Faster beeping or a solid alarm indicate a
larger concentration of combustible gas.
NOTE: GAS-Mate will automatically zero to the background concentration,
indicated by the alarm slowly returning to a steady beep. Once
zeroed, only a higher concentration will cause an alarm.
5. Move the probe tip slowly (approximately 1 to 2 in. (2.5 to 5 cm) per second)
around suspected leak sites. Position the probe tip as close as possible to the
suspected leak site for optimum performance.
6. To confirm a leak, pull the probe away from the suspected leak site and allow
the instrument to return to a steady state. Repeat step 5.
NOTE: After exposure to very high concentrations of some gases, the sensor
may require several minutes to stabilize and return to normal
operation.

How to Change the Sensor
The sensor comes installed in the tip of the GAS-Mate probe. You only need to
insert/remove the sensor when it is time to replace it.
NOTE: If all leak indicators flash and a steady alarm occurs, the sensor is bad or
not installed properly. Ensure the sensor is installed properly or install a
new sensor if this occurs.
1. Insert a paper clip or a small screwdriver under the sensor through the slot in
the probe tip and carefully slide the sensor out of the end of the probe tip as
seen in Figure 2.
2. Remove the new sensor from its packaging.
3. Align the tab on the sensor can with the slot in the probe tip.
4. Carefully slide the sensor into the probe tip. Ensure the wire leads fit into the
matching holes in the sensor socket in the probe tip.
NOTE: When properly installed, the top of the sensor should be
approximately flush with the tip of the probe. It is acceptable if the
probe protrudes slightly from the probe tip as long as the sensor is
fully seated.

Cleaning and Storage
GAS-Mate's plastic housing can be cleaned with standard household detergent or
isopropyl alcohol. Care should be taken to prevent the cleaner from entering the
instrument. Since gasoline and other solvents may damage the plastic, protect
your INFICON GAS-Mate from contact with these substances.
NOTE: Do not allow cleaners or isopropyl alcohol to enter the sensor as it may
become contaminated. Replace the sensor if contamination occurs.

Batteries are
improperly installed.
Refer to Figure 1 for
proper installation.
Poor sensitivity.
GAS-Mate powers up,
but does not detect
combustible gas.
Unit set to low
sensitivity.
Increase sensitivity by
swiping up on touch
pad.
Sensor is worn out and
needs to be replaced.
Replace sensor.
Alarm sounds
continuously, even after
a couple minutes of
warm-up.
The sensor is not
installed properly or is
missing.
Ensure sensor leads
are straight and
inserted in the holes at
the base of the sensor
socket and the
orientation tab is
properly aligned in the
probe tip. Refer to
Figure 2.
Sensor is worn out and
needs to be replaced.
Replace sensor.
