VOC (Volatile Organic Compound) detection works by using a photoionisation detector (PID). In simple terms the PID detectors ionise a small sample of the VOC gas using ultraviolet light. As the sample gives up the electrons it gained during ionisation the detector measures the flow of electrons, which is proportional to the amount of gas present. This can then be processed to provide a gas reading. Different VOC gases have different ionisation potentials. IGD offers clients a 10.6 EV PID sensor which can measure 700+ VOC gases and vapours. Isobutylene is used as a safe stable calibration gas with cross calibration factors available to relate to the gas in question.

With over 100 years of dedicated gas detection experience and over two decades of manufacturing, supplying, and servicing PID detectors you will receive the highest quality of service and support.  Specialising solely in gas detection you can be sure that you are getting detectably better safety advise and equipment from a specialist source. We offer free training on all our products and demonstration units for portable monitors. We are a CPD accredited source and have team covering the UK and Ireland, as well as offering online and in person training. In addition, we have one of the largest distributor and partner networks in the industry.

This ensures, you can get the highest quality PID detectors and training on PID detectors, wherever you are, straight from the manufacturer. Check out our new, advanced range of fixed and portable PID detectors below.
