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 photoionizaton detector is an efficient and inexpensive detector for many gas and vapor analytes. A PID may produce instantaneous readings and operate continuously. These hand-held, battery-operated detectors are widely used in military, industrial, and confined working facilities for safety.

FirstCheck+ FirstCheck+ is the first PID multi-gas to combine volatile organic compounds (VOCs) and toxic gas detection with traditional mult-igas sensors for oxygen, hydrogen sulphide, carbon monoxide and explosive gases. Its unique patented Fence Electrode Technology incorporates a three-electrode format ensuring proven resistance to humidity and contamination, giving optimal user performance in the form of accuracy and repeatability in the field. It has an inert flow path where the sample enters the PID first, then the multi-gas module then exits via the pump. more
