The ExDetector HC 150 is used to measure the current concentration of explosive gases and vapors.

With the ExDetector HC 150 explosive gases and vapors can be detected in the measuring range from 0 to 100 % LEL. The measuring principle is based on catalytic combustion (pellistor). A large number of gases, e.g. hydrogen and hydrocarbons, can be monitored with this measurement principle.

It additionally meets all criteria for use in Ex zone 2 and in areas of functional safety according to SIL-1. 

Variant: ExDetector HC 150 K

The ExDetector HC 150-K sensor was specially developed for duct installation.
