The Parasense GRM2 Refrigerant Monitor is a multi-channel aspirated monitor which provides uncompromising sensitivity to leaks of different refrigerants. The GRM2 Monitor can sample air from up to 16 points around your refrigeration system, depending on your requirements, the GRM2 can also provide monitoring for 1, 4, 8, or 12 channel configurations with a range of output options.

The Parasense GRM2 utilizes one sampling pump and alarm per channel which provides enhanced reliability and longevity. The modular design of the GRM2 refrigerant monitor also means that should one component require maintenance, it can easily be replaced when required, rather than remove the entire unit from circulation.
