sensore voc

+

All VOC sensors are calibrated at the Aeroqual factory using isobutylene. This means in the presence of 1 ppm isobutylene all three sensors will report 1 ppm. The isobutylene conversion factor from ppm to mg/m3: 1 ppm = mg/m3. However in the presence of other volatile organic compounds, the response will be very different for each sensor type.

FACTORS AFFECTING THE CHOICE OF VOC SENSOR

+

PhotoIonisation (PID) VOC sensors PIDs respond to most VOCs except for small hydrocarbons such as methane, and for some halogenated compounds. Each VOC has a characteristic ionisation potential and the peak photon energy generated in a detector depends on the PID lamp used. For example, a Xenon lamp = eV, a Krypton lamp = eV and an Argon lamp = eV. Hence, the use of an argon …
