AM4203-FC A2L Refrigerant Leak Detection Sensor CH4 sensors These micro gas sampling pumpsThe AM4203 FC A2L Refrigerant Leak Detection Sensor detects A2L gases (including R32, R454A, R454B and R454C), and A3 gas R290. Based on NDIR (Non Dispersive Infrared) technology, AM4203 Series could detect and monitor refrigerant gas leakage and provide early warning. It has the advantages of fast response, excellent accuracy and good long term stability. Full auto baseline calibration mechanism also secure free of maintenance during its life span.
