WatchGas QGM Multi-Gas Detector

WatchGas QGM Multi-Gas Detector

WatchGas QGM detects oxygen, hydrogen sulfide, carbon monoxide, and combustible gases (LEL).

The WatchGas QGM detects oxygen, hydrogen sulfide, carbon monoxide, and combustible gases (LEL). When the concentration of these gases exceeds the alarm threshold, the WatchGas QGM warns the user with vibrations, LED flashing, and a 90dB acoustic alarm. The integrated data and event logger records measurements, peak values, average values, alarms, calibration dates, and bump test information for up to two months. All logs can be downloaded to a PC using the WatchGas IR-link software. The QGM can be used as a monitor for 1 to 4 types of gas detectors. It comes standard with a contact combustion-type LEL sensor, and it is also possible to equip the QGM with an NDIR LEL sensor. The NDIR LEL sensor consumes less power and achieves a battery life of up to two months on a single charge. The IR LEL sensor has several other advantages, including the ability to measure combustible gases in the absence of oxygen, making it suitable for use in environments where oxygen concentration varies. It is also less affected by silicon and sulfur. Furthermore, the QGM is capable of measuring oxygen, carbon monoxide, and hydrogen sulfide.
