Four-gas detector for surveying levels of H2S, oxygen (O2),
carbon monoxide (CO), and combustibles in natural and industrial
environments, and in other personal safety, training, research,
and ambient air monitoring applications.
• Electrochemical cell sensor measures H2S and carbon monoxide
levels in ppm, capillary-pore fuel cell measures oxygen in percent
by volume, and catalytic bead combustible sensor measures
explosive gases in - percent LEL.
• Audio, visual, and vibration alarms alert simultaneously when
ambient H2S, oxygen, carbon monoxide, and combustible gases
reach preset low, high, TWA, or STEL levels.
• LCD screen shows up to four ambient gas concentrations,
battery level, alarm condition, and the status of calibration,
bump, and sensor self-tests.
• Integrated diaphragm pump allows for localized sampling
of the atmosphere for more precise
