Cubic - Model CRG Series -A2L Refrigerant Gas Sensor

Cubic refrigerant gas sensors and solutions mainly target the A2L mixtures,e.g. R32, R1234yf gas or that of a pure hydrocarbon in the blend, and calculates the air volume concentration of the refrigerant gas and relates it to the avoidance thresholds by levels of LFL (Lower Flammability Limit) or LEL (Lower Explosion Limits). It is based on NDIR (Non-Dispersive Infrared) technology with high accuracy and longer lifespan. This sensor has been developed with standard gas and is efficiently calibrated in the factory by Cubic own gas sensor calibration technology. The sensing solutions can output an alert or directly participate in mitigation or shut-down procedures.
