GENERAL DESCRIPTION
The SENSIT® HXG-2d is designed to detect combustible gases. This
instrument incorporates an advanced low power semiconductor sensor to
measure a wide variety of combustible gases in both the PPM and %LEL
range. The PPM readings auto-range to %LEL when the concentration
exceeds 990PPM (2%LEL methane or 4.5%LEL propane).
Optionally all readings can be set to a resolution of 0.1%LEL only (PPM
off). An “on demand” backlight allows use in dark environments. A user
activated “TICK” control assists in locating small gas leaks.
Audible and visual alarms warn the operator of hazards. The alarms can
be set in either the PPM or LEL modes. The default alarm is 10%LEL
methane/propane.
The instrument is adjusted at the factory for either methane or propane
as the primary gas, and is calibrated accordingly. The primary gas can be
selected when ordering.
The SENSIT® HXG-2d meets US UL913 requirements when used with
approved batteries.
The SENSIT® HXG-2d is operated using approved alkaline batteries
only.
⚠ Warning: Never mix batteries of different age or type.

PRODUCT FEATURES
SENSIT® HXG-2d instruments are constructed of durable high impact
ABS to withstand the rigors of eld use.
Incorporated in the hand grip area is the battery compartment. All
SENSIT® HXG-2d instruments require 3. Duracell PC1400 batteries
provide approximately 50 hours of continuous use.
A push button located in the center of the instrument activates an
audible tick sound that will help in locating the source of a gas leak. This
tick is generated by using specialized circuitry in combination with the
LEL sensor located at the end of the gooseneck assembly. The tick can
be easily heard with the speaker located in the back of the instrument.
A exible gooseneck is used to assist in locating the source of gas leaks
and remote sampling.
The display continuously updates the operator of changes in gas
concentrations and alerts of low battery power.
A green LED on the left side indicates the instrument is ready for use. A
red LED indicates the preset alarm points have been exceeded.

instruments.
BUTTON (A) POWER/MUTE
Operates the POWER and MUTE features and exit menu items.
BUTTON (B) TICK/CAL
Use to operate TICK or begin calibration.
BUTTON (C) LIGHT/ZERO
Use to turn on the backlight or manually zero the sensor.

SENSOR TYPE
COMBUSTIBLE GAS SENSOR
All SENSIT® HXG-2d instruments incorporate a highly sensitive
semiconductor type sensor. The function and accuracy of the sensor are
monitored and controlled by specialized circuitry and a microprocessor.
This sensor is capable of measuring concentrations of 10ppm of
methane/propane up to 100% LEL. Factory calibration uses methane
or propane depending on preset gas type.. This sensor will detect many
combustible gases.
SENSOR FILTER REPLACEMENT / CLEANING
Remove sensor cap by pressing retaining tab located on side of sensor
and pulling the cap away from base. Filter will be loose inside. Clean
lter with mild soap and water and thoroughly dry lter cap. Replace
Cap/Filter on base until retaining tab engages.
NOTE: Operating the instrument without a sensor cap or with an altered
sensor cap can cause damage to the instrument and void the warranty.
