1 PC ZRT510 Refrigerant R290 Sensor Module

ZRT510 refrigerant R290 sensor module is a smart infrared type sensor module, using non-dispersive infrared (NDIR) principle to detect the existence of refrigerant, with good selectivity and non-oxygen dependent. It is a compact high performance sensor module made by combining mature infrared gas detection technology with micro machining and sophisticated circuit design. It is easy to use with excellent performance.
