Photo Ionization Detector . Description. The Photo Ionization Detector (PID) is a portable vapor and gas detector that detects a variety of organic compounds. Photo ionization occurs when an atom or molecule absorbs light of sufficient energy to cause an electron to leave and create a positive ion A Photo-Ionization Detector (PID) measures real-time concentrations of organic and inorganic vapors in low levels from parts-per-billion (ppb) up to 10,000 parts-per-million (ppm). A PID is a very sensitive instrument used in a wide variety of applications such as Photo Ionisation Detectors (PID) are portable gas and vapour detectors that detect a variety of Volatile Organic Compounds (VOC's) using a UV ionisation principal of operation. A PID lamp can measure VOC's in very low concentrations from ppb (parts per billion) up to 10,000ppm (parts per million/ 1% Volume) Photo Ionization Detectors (PID) Photo Ionization Detectors measure VOCs and other toxic gases in low concentrations from ppb (parts per billion) up to 10,000 ppm (parts per million or 1% by volume).
