Placing VOC Sensors for Assessing Air Quality

metering volatile organic compounds (VOC), temperature, and relative humidity, in place of the airflow metering of the traditional OVK solution. One of the first issues encountered was sensor placement, as the sensors must be discreetly installed on available surfaces while the collected air quality data must represent the air in the occupied zone.

VOC Sensors and Monitors - Volatile Organic Compounds

Both sensor types are non-selective which means they can be used for measuring a wide variety of VOCs. To achieve this they have been calibrated against isobutylene that allows them to respond to a wide range of VOCs at varying degrees of sensitivity. Each type has a calibrated measurement range against a set of VOCs.

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 ...
