Portable Photoionization Detectors (PID) are advanced devices that use high-energy UV light to monitor volatile organic compounds (VOCs) in the air. These detectors can accurately detect over 300 VOCs, requiring specific lamp selection. Some popular PID models include the GMI PS500, ToxiRAE Pro PID Gas Detector, MiniRAE 3000, MiniRAE Lite Monitor, Industrial Scientific Ventis Pro 5 PID Multi-Gas Monitor with LENS Wireless connectivity, Drager X-pid 9000/9500, MultiRAE Lite Pumped, ppbRAE 3000, ToxiRAE Pro PID Gas Detector, MiniRAE Lite Monitor, MultiRAE Lite Pumped, and MiniRAE 3000 Photoionisation (PID) Detector.
Calibrating a PID is crucial for accurate measurements of VOCs and other gases. To calibrate a PID, prepare a calibration gas cylinder with a known concentration of the target gas, power up the PID, zero out the sensor in fresh air or a clean environment, expose the sensor to the calibration gas, adjust calibration settings, and verify calibration. Regular calibration ensures the PID provides reliable and accurate readings, and it is essential to follow the manufacturer's specific instructions for your specific model.
