VOC Sensors and Monitors Volatile Organic Compounds

Aeroqual offers two types of VOC measurement sensors; Photoionization Detector (PID), and Gas Sensitive Semiconductor (GSS). Both sensor types are nonselective 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. PID type VOC sensors …
