conditions which are listed by OSHA or others as potentially haz-

ardous to personnel and property, the information in this manual

must be fully understood and utilized to ensure that the instrument

is operating properly and is both used and maintained in the proper

manner by qualiﬁed personnel. An instrument that is not properly

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.

Leakator 10

Instruction 0019-9167

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.

IntroductionLeakator 10

Instruction 0019-9167

•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

Introduction

Instruction 0019-9167

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.
