VOC Sensors and Monitors - Volatile Organic Compounds

Mixed VOC measurement are commonly used to detect the presence of VOCs in uncontrolled environments ( offices, outdoors) to determine air quality. In this scenario the measurement is used as a relative indicator of the presence and level of VOCs in the environment. Some VOCs will influence the reading more than others – known as cross-interference – the measurement is therefore only a …
