WebAn ionization smoke detector is a fire alarm system with a built-in ionization chamber supported by two plates with voltage between them. Electrons present between the two plates are displaced by smoke entering the chamber, which in turn causes an alarm to go off. This alarm system has a proven potential to save lives, prevent burn injuries ...
A photoionization detector or PID is a type of gas detector. Typical photoionization detectors measure volatile organic compounds and other gases in concentrations from sub parts per billion to 10 000 parts per million (ppm). The photoionization detector is an efficient and inexpensive detector for many gas … See more In a photoionization detector high-energy photons, typically in the vacuum ultraviolet (VUV) range, break molecules into positively charged ions. As compounds enter the detector they are bombarded by high-energy UV … See more The first commercial application of photoionization detection was in 1973 as a hand-held instrument for the purpose of detecting leaks of VOCs, specifically vinyl chloride monomer (VCM), at a chemical manufacturing facility.
