Cubic - Model SRH Series -Industrial Grade CO2 Sensor

Miniature industrial grade NDIR CO2 sensor adopts NDIR technology to detect CO2 concentration in industrial applications. It adopts advanced non-dispersive infrared technology (NDIR), which can be integrated in safety and alarming devices, able to be used for CO2 incubator, greenhouse, environmental monitoring, HVAC, refrigerator, cold storage.

The sensor contains all the necessary optics, electronics and firmware to provide a linearised, temperature_x0002_compensated output. It is with a heated infrared source inside a small chamber. In this case, the inside temperature of the gas sensor is much higher than the outside which can avoid condensing events and the high humidity influence. Besides, the PCB inside the gas sensor is specially treated for corrosion protection.
