CO2 Sensors vs. VOC Sensors for IAQ - What's the ...

People sometimes ask about the differences between VOC (Volatile Organic Compounds) sensors and CO2 sensors. While both can be used to measure indoor air quality (IAQ), these sensors are not interchangeable. They measure very different things. CO2 sensing technology by IR (infrared) is stable and is not subject to the short-term, random drift found in air quality sensors. Most IR carbon ...

Gas Sensor Applications |

The most accurate method of CO2 sensor calibration is to expose it to a known gas (typically 100% nitrogen) in order to duplicate the conditions under which the sensor was originally calibrated at the factory. ISO certification is available on our high‐end sensors to verify this process for medical or scientific purposes. Nitrogen calibration is also required if CO2 levels between 0‐400 ppm will be …
