CO2 Sensor Measurement Range, Accuracy and Precision ...

As a rule, the narrower the range of CO2 measured, the higher the accuracy of the sensor. For example, if you were measuring 400ppm CO2 (fresh air) using a 100% CO2 sensor and the CO2 level increased to 500ppm, the change would be from % to %. This % (100ppm) change is outside the 100300ppm range of accuracy of a typical 100% CO2 ...
