The MultiRAE Plus PID combines a Photoionization Detectorwith the standard four gases of a confined space monitor (O2, LEL, and two toxic gas sensors) in one compact monitor with sampling pump. O2, LEL, PID, H2S l  0-2,000 ppm l  0.1 ppm resolution 

The GEM2000 portable instrument is designed for analyzing Landfill Gas (LFG) composition and calculating flow. The GEM2000 combines the capabilities of the now discontinued GA-90 for monitoring gas migration probes and the GEM-500 for monitoring gas extraction systems.

The GasWatch 2 is the first single-gas monitor that can be comfortably worn on the wrist like a watch. Choose from CO, H2S, or O2. 

These portable gas monitors from GasTech are designed for rugged, all-weather use. Use the GT 201 two-gas monitor or the GT-402 four-gas monitor to protect workers from hazardous gases in confined spaces or other work sites. The GT 201 monitors oxygen volume and hydrocarbons. The GT 402 monitors oxygen, carbon monoxide, hydrogen sulfide and hydrocarbons.
