DEGA NSx-PL III PID with a PID – photoionization sensor
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
and vapor analytes. PIDs produce instantaneous readings, operate continuously, and are commonly used as detectors for gas
chromatography or as hand-held portable instruments. Hand-held, battery-operated versions are widely used in military,
industrial, and confined working facilities for health and safety. Their primary use is for monitoring possible worker exposure
to volatile organic compounds (VOCs) such as solvents, fuels, degreasers, plastics & their precursors, heat transfer fluids,
lubricants, etc. during manufacturing processes and waste handling.
