A2L Refrigerant Gas Sensor-AM4205 SeriesAM4205

Cubic NDIR refrigerant gas sensor AM4205 mainly targets at A2L gas, such as R32, R454A, R454B, R454C, or A3 hydrocarbon like propane R290.
Based on NDIR (Non-Dispersive Infrared) technology, AM4205 could detect and monitor refrigerant leak then provide early warning, it has advantages of fast response, high accuracy and good long-term stability.
The sensor has been developed with standard gas and is efficiently calibrated in the factory by Cubic own calibration technology. The sensing solutions can not only output an alert, but also directly participate in mitigation or shut-down procedures.
AM4205 sensor is widely used for detecting or monitoring refrigerant leakage in these fields, such as commercial /transport /industrial refrigeration, automotive air conditioning, commercial air conditioning, heat pumps, etc.
