Hydrogen Gas Sensor


Exchangeable sensor unit including digital value processing, temperature compensation and self-control for the continuous monitoring of the ambient air.

MC2 Gas Detector
MC2 Gas Detector

The sensor unit MC2 houses a module with μController, analog output and power supply in addition to the infrared or Pellistor sensor element including amplifier. The μController calculates a linear 4–20 mA (or 2–10 V) signal out of the measurement signal and stores all relevant measured values and data of the sensor element.

Calibration is done either by simply replacing the sensor unit or by using the comfortable, integrated calibration routine directly at the system.
