Description
The WatchGas QGM is a versatile multi-gas monitor engineered to keep you and your staff safe while working in hazardous environments. The QGM offers detection for up to four different gases:
- Oxygen
- Hydrogen sulphide
- Carbon monoxide
- Pentane
- Combustible gases (LEL)
When the concentrations of these gases exceed the alarm thresholds, the QGM alerts the user by vibrating, flashing LEDs and a 90dB acoustic alarm. An integrated data and event logger records measured 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.
