Refrigerant Gas Sensor KGD - AM - 204
Product Introduction
The KACISE NDIR refrigerant gas sensor KGD - AM - 204 developed by KACISE Optoelectronic mainly targets A2L gases, such as R32, R454A, R454B, R454C, and R290. Based on NDIR (Non-Dispersive Infrared) technology, the KGD - AM - 204 can detect and monitor refrigerant leakage and provide early warnings. It has the advantages of fast response speed, high precision, and good long-term stability. This sensor is developed using standard gases and is effectively calibrated through KACISE 's own calibration technology. It is widely used in the detection or monitoring of refrigerant leakage in commercial/transportation/industrial refrigeration, automotive air conditioning, commercial air conditioning, heat pumps, and other fields.
