CO2 Sensor Measurement Range, Accuracy and Precision ...

20071220· As part of a quality assurance (QA) study for sensor systems, an enclosure approach is applied to assess the accuracy of nondispersive infrared (NDIR)based CO 2 sensors. To examine the performance of the sensor system, an enclosure chamber containing six sensor units of the two model types (B530 and H500) was equilibrated with calibrated CO 2 standards at varying concentration levels.
