Photoionisation Detection (PID) is the recommended technology to detect VOC levels in the air. PIDs break down compounds into positive and negative ions using ultraviolet light to identify VOCs. PID sensors analyse and detect a vast array of chemicals, though humidity is a major challenge for many PID manufacturers, however, all of ION’s MiniPIDs have a patent-protected design with a third electrode that overcomes this challenge, delivering a stable signal from 0 – 99% RH. The sensitivity of PID sensors is extremely important in many applications; particularly where the sensors are deployed in the measurement of trace VOCs. Again, ION leads the field, offering MiniPIDs with ten times the sensitivity of other PID manufacturers.
