GasAlertMax XT II
Introduction
a Warning
To ensure personal safety, read Safety Information -
Read First and aCautions before using the detector.
The GasAlertMax XT II gas detector (“the detector”) warns of
hazardous gas at levels above user-defined alarm setpoints.
The detector is a personal safety device. It is your respons bility
to respond properly to the alarm.

Gases Monitored
The following table lists the gases that are monitored by the detector.
Table 1. Gases Monitored
CAUTION: FOR SAFETY REASONS, THIS EQUIPMENT MUST BE
OPERATED AND SERVICED BY QUALIFIED PERSONNEL ONLY.
READ AND UNDERSTAND THIS TECHNICAL REFERENCE GUIDE
COMPLETELY BEFORE OPERATING AND SERVICING.
Safety Information - Read First
Use the detector only as specified in this technical reference guide,
otherwise the protection provided by the detector may be impaired.
International symbols used on the detector and in this technical
reference guide are defined in Table 2.
Read the aCautions on the following pages before using the detector.
ec Warning
This instrument contains a lithium polymer battery.
Dispose of lithium cells immediately. Do not
disassemble and do not dispose of in fire. Do not mix
with the solid waste stream. Spent batteries must be
disposed of by a qualified recycler or hazardous
materials handler.
Gas Detected Unit of Measure
Hydrogen sulfide (H2S) parts per million (ppm)
Carbon monoxide parts per million (ppm)
Combustible gases (LEL)
a) percent of lower explosive limit
(%LEL)
b) percent by volume methane
0-5.0% v/v
Oxygen (O2)% volume
