calibrated, operated and maintained by qualified personnel is likely
to provide erroneous information, which could prevent user awareness
of a potentially hazardous situation for the instrument user, other
personnel and property.
If, after reading the information in this manual, the user has questions
regarding the operation, application or maintenance of the instrument,
supervisory or training assistance should be obtained before use. Fac-
tory assistance is available by calling 1-800-736-4666.
WARNING!
The Leakator 10 is not to be used in any application that is beyond
its intended purpose or beyond the scope of its specifications. Failure
to follow this warning can result in personal injury or damage to the
equipment. For details on appropriate use, refer to the general descrip-
tion, application, and operation discussions in this manual.

1.0 GENERAL DESCRITPION AND USE
The Leakator 10 is an intrinsically safe, battery-powered
portable instrument designed to primarily detect the source
of combustible-gas leaks. The instrument is ideally suited
for heating service contractors, utility personnel, and other
users who are interested in pinpointing gas leaks, and test-
ing gas appliances in residential, commercial and industrial
installations.
The instrument is supplied with a durable plastic carrying
case, 20" probe and instruction manual.
The Leakator 10 features:
•Ten bright-red LEDs and a speaker that provide visual
and audible indications to the presence of gas.

•Three operation-status LEDs that show power on, sensor
operation, and low battery.
•A 20-inch flexible probe.
•Simple thumb wheel on/off and gain control allowing one-
handed operation.
•A solid-state sensor that has a typical life of 5 years.
•A battery capacity of 30 hours under normal use conditions.
•The ability to detect natural gas (methane) in concentrations
as low as 20 ppm. In addition, the following gases and vapors
are also detectable:
Acetone Ethanol IndustrialSolvents
Acetylene Ethylene Oxide Paint Thinners
Ammonia Gasoline Propane
Benzene Hexane Naphtha
Butane Hydrogen

WARNINGS!
For safety reasons, the Leakator 10 must only be operated
and serviced by qualified personnel. Read and understand
the contents of this instruction manual before operating
or servicing.
To prevent ignition of a hazardous atmosphere, do not
perform any maintenance work, such as replacing the in-
strument’s batteries, sensor, or sensor-matching resistor,
in an area classified as being hazardous.

3.0 BATTERY INSTALLATION
WARNING!
Do not replace batteries in a hazardous area.
CAUTION:
To maintain agency approval, use only
NEDA-14A type batteries or equivalent.
Remove battery cover. Install five (non-rechargeable) 1.5V
C-size alkaline batteries per Figure 2 – observe proper polar-
ity. Then reinstall battery cover.
4.0 OPERATION
4.1 Turning ON the Instrument
Turn ON the instrument by rotating its thumb-wheel switch

(Fig 3) clockwise until a click is heard. Observe the following:
•The Power LED lights.
•The Fail LED will light, but should turn off in a few sec-
onds if the sensor is good and properly seated in its socket.
•If the Low Bat. LED is on, replace the batteries per Section
3.0 Battery Installation.
After the instrument stabilizes, rotate the Gain control in the
direction necessary to cause the bottom Gas Level LED to
just turn off. Be sure to always set this control in the same
environment you intend to test in.
The instrument is now ready for use.
4.2 Taking a Gas Reading
To verify that the instrument is operating, sample a known
combustible gas (e.g., a gas-air mixture from an unlit burner
of a natural-gas range). If no response is observed or heard,
refer to Section 6.0 Troubleshooting.
Important! The sensor becomes less sensitive
after being exposed to an excessive amount of
gas. Therefore, after testing the instrument as
described above, leave it on for several minutes
to restabilize the sensor.
Take a gas reading by positioning the end of the instrument’s
flexible probe near the area to be sampled.
The presence of a combustible gas is indicated by a column of
ten red LEDs and a speaker. The number of lighted LEDs gives
visual indication of the relative gas level, while the speaker
produces clicking sounds, similar to a Geiger counter, that
increase in repetition rate as the gas concentration goes up
in relation to the instrument’s gain setting.
The instrument’s sensitivity to gas concentrations is adjusted
by means of its thumb-wheel Gain control. Clockwise rotation
increases sensitivity, while counterclockwise rotation decreases
sensitivity. The Gaincontrol is useful in pinpointing large leaks
by starting with the control set to light 1 or 2 LEDs, and then
gradually rotating the control counterclockwise as the probe
gets closer to the leak.
