About the GX-3R
Using an advanced detection system consisting of up to three gas sensors, the GX-3R
personal four-gas monitor detects the presence of combustible gas, oxygen (O2), carbon
monoxide (CO), and hydrogen sulfide (H2S) simultaneously. The GX-3R’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-3R offers a full range of features, including:
• Simultaneous monitoring of one to four gases
• Liquid crystal display (LCD) for complete and understandable information at a glance
• Ultrabright alarm LEDs
• Distinctive audible/vibrating alarms for dangerous gas conditions and audible alarms
for unit malfunction
• Microprocessor control for reliability, ease of use, and advanced capabilities
• Data logging functions
• Alarm trend data
• STEL, TWA, and over range alarms
• Peak readings
• Built-in time function
• Lunch break feature
