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 non-dispersive infrared (NDIR) carbon dioxide sensors.
