MGS11 Series

Refrigerant sensor

The MGS11 series gas sensor module adopts the NDIR gas measurement principle and combines a gold-plated gas chamber with a high-precision sampling circuit. It has built-in temperature compensation and self-calibration functions. It can accurately measure the gas concentration of R32, R454B, R410A in the environment. It has long service life, high measurement accuracy, It has the advantages of good gas selectivity and stable performance.
