Portable Photoionisation (PID) Detectors and and VOC Monitors

Photoionisation Detectors (PID) and VOC Detectors provide you with the cabability to detect a much wider range of gases than standard multi gas monitors such as Jet Fuel, Kerosene and Styrene.  Photoionization detectors use high-energy ultraviolet light from a lamp housed within the detector as a source of energy used to remove an electron from neutrally charged VOC molecules, producing a flow of electrical current proportional to the concentration of contaminant.

The lamps that Safety Gear Store offer are 9.6 eV, 10.6 eV and 11.7eV, the 10.6 eV lamp is the most common because it has strong output, has the longest life and responds to many compounds. In approximate order from most sensitive to least sensitive, these compounds include:- Aromatics, Olefins, Bromides & Iodides, Sulfides & mercaptans, Organic amines, Ketones, Ethers, Esters & acrylates, Aldehydes, Alcohols, Alkanes and Some inorganics, including NH3, H2S, and PH3
