MSR-Electronic GmbH_MGC.png

Exchangeable sensor heads with digital and analog output signal.

MSR-Electronic develops individual gas sensors, e.g. for CO2, CO, CH4, CH2O, NH3, O2 or H2 and systems in which toxic or combustible gas concentrations can form.


These are integrated into complex warning systems and are used, for example, in parking garages, biogas plants, refrigeration systems, petrochemical industrial plants, breweries and dispensing systems or in laboratories and medical applications as well as in hydrogen production and processing.
