Carbon dioxide : Sensing element: Non-Dispersive Infrared Detector (NDIR) CO2 measuring range . 0~2000ppm (default) 0~5000ppm (selected in the advanced setup) CO2 Accuracy @22℃(72℉) ±60ppm + 3% of reading or ±75ppm (whichever is greater) Temperature dependence: % FS per℃ Stability <2% of FS over life of sensor (15 year typical)
The Carbon Dioxide value can be output to PC for on-line analysis. The CO2 sensor can be calibrated easily in the fresh air, and the RH sensor could be calibrated with AZ 33%/75% salt bottle. The 7755 AZ CO2 device could be used as the CO2 checker for the air quality index in all workspace, office, hospital, school, station or home.
