QGM

Versatile up to 4-Gas Personal Multi-Gas Detectors

The WatchGas QGM is a sustainable multi-gas monitor engineered to keep you and your staff safe while working in hazardous environments. The WatchGas QGM offers detection for up to four different gases. The WatchGas QGM can detect the deficiency of Oxygen (O2), poisoning by Hydrogen Sulphide (H2S) and Carbon Monoxide (CO), and the lower explosion level of combustible gases present. When the concentration of these gases exceeds the pre-determined values of the TWA, STEL, high and low alarm, the WatchGas QGM will raise the alarm through vibrating, flashing LEDs and a 90dB acoustic alarm. A built-in data- and event logger registers peak and average alarm values, calibration dates, and bump test information for up to 2 months. All logs can be downloaded to the PC through the WatchGas IR-link software.

The QGM is available as a 1 to 4-gas monitor and it comes with a catalytic sensor or optional IR sensor to detect combustible gases. If the optional IR-sensor is used, the QGM’s battery life changes. The low energy-consuming sensor utilizes far less capacity than the pellistor enhancing battery life to 2 months allowing continuous operation with only one initial charge.
