PolyGard NH3 / Freone / CO2 - Sensors are used for the detection of leakages in cooling systems. Refrigerants are highly toxic and/or harmful to the environment. Accidental escape of the refrigerant is to avoid at any case. The MSR transmitters detect reliably any escape of the refrigerant gas and protect in combination with the MSR controllers and warning devices primarly persons, but also the plant. MSR Electronic products comply with current regulations.


MSR delivers sensors, controllers and accessories for cooling systems.

We have pointed out some features of the datasheets to give you a short overview.
