Industrial Gas Sensors

CRIR Series

Standard range of 400 ppm to 2000 ppm, up to 10000 ppm extended range. Accuracy of ±40 ppm ±3% of reading and ±50 ppm ±5% of reading

The CRIR Series are single channel, non-dispersive infrared (NDIR) sensors. Within the CRIR M1 and CRIR E1 is a sensing chamber with an infrared source at one end and a detector fitted with an optical filter at the other end. The source emits radiation at wavelengths which include the absorption band of CO2.

The filter blocks wavelengths which are not sensitive to the presence of CO2, thereby increasing selectivity and sensitivity. As the light passes through the sensing chamber, a fraction is absorbed if CO2 is present. The difference between the light emitted by the source and received by the detector can then be converted to a CO2 concentration reading.

The Automatic Baseline Correction (ABC) function can automatically calibrate the sensor’s lowest reading over a pre-configured interval to 400 ppm CO2. This enhances long term stability and may eliminate the need for calibration.
