About the GX-2012
Using an advanced detection system consisting of up to five gas sensors, the
GX-2012 sample draw gas monitor detects the presence of combustible gas,
oxygen (O
2
), carbon monoxide (CO), and hydrogen sulfide (H
2
S)
simultaneously. The GX-2012’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-2012 offers a full range of features, including:
• Simultaneous four-gas monitoring of combustible gases, O
2
, CO, and H
2
S
(in Normal Mode)
• Choice of two operating modes: Normal Mode for typical confined space
or area monitoring and Bar Hole Mode for checking of bar holes when
searching for underground gas leaks
• Sample-drawing pump with up to 50-foot range
• Liquid crystal display (LCD) 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
• Alarm trend data (when used in Normal Mode)
