GasMonitor 30

The Bieler+Lang GasMonitor 30 (GM 30) is a compact and universal gas detector with 4-20 mA analog output. Depending on the gas sensor installed in the detector housing, it can detect many toxic gases and vapors as well as oxygen quickly and reliably.

As an essential component of a permanently installed gas warning system, the GM30 can warn of dangerous gases in good time and initiate measures to protect people, the environment, systems and buildings.

Areas of application:

The GM 30 is designed for room monitoring in non-hazardous areas. Possible applications include laboratories, boiler rooms, process industries at
ventilation control The GM 30 is an individual component of a permanently installed gas detection system that is tailored to the location and purpose of use. The GM 30 was developed for industrial, commercial or private use in a suitable installation environment and is used for reliable long-term monitoring in the hazardous areas of the “safe area”.
