WatchGas QGM

The WatchGas QGM can detect the oxygen concentration and hazardous concentrations of H2S, CO and flammable gases. When the concentration of these gases exceeds the preset values for TWA, STEL, high and low alarm, the QGM raises the alarm with a vibrating alarm, flashing LEDs and a 90 dB audible alarm. A built-in data and event log records peak and average alarm values, calibration data and bump test information with a capacity of two months. All stored data can be downloaded to your PC with the WatchGas IRlink software.

The QGM is fitted with a catalytic LEL sensor or, optionally, with an IR LEL sensor. The IR LEL sensor uses so little power that the QGM-IR can be used continuously for two months on a single battery charge.
