Bieler + LangModel HC 200 -Explosive Gas Detectors

SHARE

The ExDetector HC 200 is used to measure the current concentration of explosive gases and vapors. The ExDetector HC 200 detects combustible gases and vapors within a range of 0 %-100 % LEL. It uses the principle of catalytic combustion (heat of reaction). The ExDetector HC 200 may be used as a stand-alone device, i.e. it can trigger safety responses independently without the use of a controller. It may also be connected conventionally to a central control unit. The ExDetector HC 200 can be used in explosion zone 2.
