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

Unlike a CO2 sensor, a VOC sensor cannot indicate the rate of ventilation needed, only the level of VOCs in the air. It also cannot necessarily indicate whether safe or harmful concentrations of VOC contaminants are present. It can indicate a general change in the concentration of contaminants. This makes air quality sensors a better solution in applications where unusual, nonoccupantrelated ...

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

CO2 sensing technology by IR (infrared) is stable and is not subject to the shortterm, random drift found in air quality sensors. Most IR carbon dioxide sensors only measure CO2. A CO2 sensor is designed to control the ventilation rate in occupied spaces. People are the principal source of CO2 in indoor air.

What''s the Difference between CO2 Sensors and VOC Sensors

20180701· When choosing sensors, it’s important to remember calibration methods are quite different between CO2 sensors and VOC gas sensors. For example, while a CO2 sensor usually requires frequent checks by engineers and maintenance technicians, a VOC sensor generally requires little if any calibration be done manually. For a CO2 sensor, this often has to do with automatic baseline …

The BAPI VOC sensor provides a CO2 equivalent ppm output so that Ashrae’s popular CO2based VRP procedure can be used for DCV; however, CO2 is not one of the VOCs that the sensor monitors. If your application needs to directly measure CO2, choose a CO2 sensor. Commissioning and Testing. BAPI’s VOC sensor is easily tested for proper operation. Many applications need to demonstrate sensor ...
