Combustibles Sensor
& Sensor Cover

Audible Alarm

• Instrument Ready - Slow beep. The beep
rate is about once per second with no gas
detected.

• Combustible Gas Indication - Beeps at
a rate that increases along with the gas
concentration.

• Sensitivity - Produces an increasing
frequency tone when sensitivity changes
from low to high, and produces a decreasing
frequency tone when sensitivity changes
from high to low.

• Dead Batteries - High frequency tone, fol­lowed by the instrument turning itself OFF.

• Sensor Error - Rapidly changing high and
low frequency tones.

Visual Alarm LED

• Power ON - Rapidly ashes green during warm-
up (approximately 60 seconds).

• Power OFF - Glows red just before power OFF.

• Instrument Ready - Slowly ashes green. The

ash rate is about once per second with no gas

detected.

• Combustible Gas Indication - Flashes green at
a rate that increases with the gas concentration.

• Sensitivity Change - Color changes from red to
green.

• Low Battery - Flashes orange instead of green
when checking for gas leaks. Typically 1 hour
of operation left after LED changes to orange.
Change batteries as soon as convenient.

• Dead Batteries - Glows red, followed by the
instrument turning itself OFF.

• Sensor Error - Flashes alternating green and red.

One Button Control

• Press once for half second to turn instrument ON.

• Press and hold for 2 seconds to turn instrument OFF.

• Double press to toggle sensitivity between high and low.

Features

• Compact Gas Leak Detector - The Leakator Jr. detects and pinpoints
combustible gas leaks in commercial, residential, and industrial applications,
including surveying gas pipelines

• Wide Variety of Combustibles Detected - Acetone, Acetylene, Benzene,
Butane, Ethanol, Ethylene Oxide, Gasoline, Hexane, Hydrogen, Industrial Solvents,
Iso-Butane, Methane, Methanol, Paint Thinners, Propane, Natural Gas, and
Naptha.

• Compact and Ergonomic Design - Simple one button control allows the

user to hold and operate the instrument in one hand. The exible probe with sensor

located at the tip allows leaks to be found in tight spaces.

• Leak Indication - The relative concentration of the combustible gas present is
indicated by the frequency of the audible and visual alarms.

• Automatic Calibration - The instrument automatically calibrates itself during
warm up when turned ON in fresh air.

• Selectable Sensitivity - High and low sensitivity mode selectable by a double
press of the ON/OFF button. Pinpoints concentrations as small as 20 ppm in the
high-sensitivity mode.

• Power - Four disposable ‘AA’ alkaline batteries provide a minimum of 14 hours of
operation. A low battery indicator warns the user when the batteries need replaced.
The instrument will also automatically turn itself OFF after a period of non-use to
preserve battery life.

• UL 913 Approved - Intrinsically safe for Class I, Division 1, Groups A, B, C, and D.

• Sensor Error Indicator

• Low Power Metal Oxide Sensor

• Microprocessor Controlled Circuitry

Testing For a Gas Leak

Align tab on sensor
with notch in socket

Combustibles Sensor

Sensor Cover

1. Turn instrument ON and allow it to warm up (approximately 60 seconds).

2. The instrument is ready to check for gas leaks after the audible alarm begins to

beep. Note that the instrument starts in its high-sensitivity mode.

3. Check for the presence of gas by positioning the tip of the exible probe near the

area to be tested.

4. An increase in the relative concentration of gas is indicated by the visual alarm’s

LED blinking faster and the audible alarm’s beep rate increasing.

5. Once the presence of the gas has been conrmed, the instrument’s sensitivity

can be lowered by double pressing the ON/OFF button (a decreasing frequency
tone should be heard), allowing the location of the leak to be easily pinpointed.
