Molecular Leakage Detector for A1, A2L, A3 refrigerant gas based on ultimate MPS technology
This refrigerant gas detector is a unique solution using the latest MPS (Molecular Property Spectrometry) technology to indicate the presence of low GWP A1, A2L and A3 refrigerant gas providing both a continous signal proportional to the gas concentration and the activation via relay for alarming once a prefixed (and settable) level is reached.
It combines all the advantages of MPS technology as in terms of long lifetime, no field calibration, built-in envirnomental compensation, no poisoning, wide temperature operating range and durability with a dedicated electronic board for easy interfacing the common control units thanks to the multiple outputs : Modbus, Relays and 4-20mA.
