WatchGas QGM Infrared

WatchGas QGM Infrared

The WatchGas QGM is a versatile multi-gas monitor designed to keep you and your staff safe when working in hazardous environments. It can detect up to four different gases: oxygen, hydrogen sulfide (H₂S), carbon monoxide (CO), and flammable gases. When concentrations of these gases exceed alarm thresholds, the QGM alerts the user with vibrations, flashing LEDs and a 90 dB audible alarm. Additionally, a built-in data and event logger records maximum and average alarm values, calibration data and functional test information for up to two months. You can easily download all data stored on your PC using WatchGas IRlink software.

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