MLD

Gas Leakage detector for HVAC-R / FC

Molecular Leakage Detector for A1, A2L, A3 refrigerant gas based on ultimate MPS technology. Hydrogen Detection READY.

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.

Replacing the inboard NevadaNano sensor, the MLD detector becomes the perfect solution for measuring hydrogen leakages in the fuel cell and in any hydrogen fuelled systems.
