MSR MC2 CO2 Gas Sensor Transmitter

Product Id : 267648

In addition with MSR MC2 CO2 sensor element with infrared sensor there is a module integrated in the sensor unit with µController, analog output and power supply. The IR measurement principle with integrated temperature compensation ensures highest accuracy, selectivity and reliability despite the long calibration interval.

Product Description

In MSR MC2 CO2 the µController calculates a linear 4 – 20 mA (or 2 – 10 V) signal out of the measurement signal of the IR sensor and also 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.


The µGard®2 Sensor is used for the detection of CO2 leaks in dispensing and refrigeration systems etc.
