Introduction
Using an advanced detection system consisting of four gas sensors, the
GX-2009 personal four-gas monitor detects the presence of combustible
gas, oxygen (O
2
), carbon monoxide (CO), and hydrogen sulfide (H
2
S)
simultaneously. The GX-2009’s compact size and easy-to-use design
makes it ideally suited for a wide range of applications, including sewage
treatment plants, utility manholes, tunnels, hazardous waste sites, power
stations, petrochemical refineries, mines, paper mills, drilling rigs, and fire
fighting stations. The GX-2009 offers a full range of features, including:
• Simultaneous four-gas monitoring and display of combustible gases,
O
2
, CO, and H
2
S
• Backlit LCD (liquid crystal display) for complete and understandable
information at a glance
• Distinctive audible/vibrating alarms for dangerous gas conditions and
audible alarms for unit malfunction
• Microprocessor control for reliability, ease of use, and advanced
capabilities
• Resistance to RF (radio frequency) interference
• Datalogging including interval trend data and alarm trend data
• STEL/TWA and over range alarm display
• Peak hold readouts
• Built-in time function
• Lightweight and compact high impact plastic case
• Rotatable alligator clip for “hands-free” gas monitoring, belt clip optional
• CSA classified for Class I, Division I, Groups A, B, C, and D hazardous
atmospheres
WARNING: The GX-2009 detects oxygen deficiency and elevated
levels of oxygen, combustible gases, carbon monoxide,
and hydrogen sulfide, all of which can be dangerous or
life threatening. When using the GX-2009, you must
follow the instructions and warnings in this manual to
assure proper and safe operation of the unit and to
minimize the risk of personal injury. Be sure to maintain
and periodically calibrate the GX-2009 as described in
this manual.
NOTE: Only the combustible gas detector portion of this instrument has
been assessed for performance.
