HFC refrigerant sensor HBLC-HFC

HBLC-HFC is designed for the measurement of HFC refrigerant level in chillers, evaporators and condensers.

The sensor detects the refrigerant and transmits the signal to an analog 4-20 mA signal.

The sensor has been pre-calibrated to HFC. It can however be calibrated also for other refrigerants.
