INIR4-R290

INIR4-R290 is a refrigerant (A3) R290 leakage detection sensor. This user-friendly digital gas sensor is designed to use the latest SGX Sensor tech’s Non-Dispersive Infra-Red (NDIR) technology. It has been primarily designed for the purpose of gas leakage detection in both industrial and residential environments. Designed with the latest generation of power-efficient CORTEX microcontrollers allows for high flexibility and functionality. Temperature compensation, good accuracy, and simple implementation into the end-user system make this sensor a perfect solution for gas leakage detection. Key application includes R32 leakage detection, residential gas monitoring, heat pumps, refrigeration, chill cabinets, vending machine, cold storage systems, and air conditioning. Meets UL 60335-2-40 / IEC 60079-29-1 / IEC60335-2-40 requirements.
