Description

The WatchGas QGM is a versatile 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: Oxygen, Hydrogen Sulfide, Carbon Monoxide and combustible gases.

When the concentrations of these gases exceed the alarm thresholds, the WatchGas QGM alerts the user by vibrating, flashing LEDs and a 90dB acoustic alarm. An integrated data- and event logger registers measure values, as well as peak and average values, alarms, calibration dates and bump test information for up to two months. All logs can be downloaded to your PC through the WatchGas IR-link software
