CO2 Sensor Calibration: What You Need to Know | …

+

All carbon dioxide sensors need calibration. Depending on the application, this can be accomplished by calibrating the sensor to a known gas or using the automatic baseline calibration (ABC) method. Both have pros and cons you should know. Most of our CO2 products use nondispersive infrared (NDIR) carbon dioxide sensors. These rely on an infrared light source and detector to measure the number …
