Versatile and rugged detector for O2, LEL, H2S and CO

The WatchGas QGM is a versatile multi-gas monitor engineered to keep you and your staff safe while working in hazardous environments. WatchGas QGM offers detection for up to four different gases and is ideal for use as a confined space entry gas monitor.

The WatchGas QGM monitors 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 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.

The QGM is available as a 2, 3 or 4-gas monitor. A catalytic LEL sensor comes as standard. Alternatively, you can specify your QGM with a Non-Dispersive Infrared Sensor. The IR LEL sensor consumes less energy, enhancing the battery life to up to two months on a single charge. The IR LEL sensor has some other advantages as well. It can measure combustible gases in the absence of oxygen, making it more useful in environments where oxygen levels may vary. Furthermore, it is less susceptible to poisoning by silicone and sulfur.
