A photoionization detector or PID is a type of gas detector that measures 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.
Portable PIDs are used as monitoring solutions for:
- Industrial hygiene and safety
- Environmental contamination and remediation
- Hazardous materials handling
- Ammonia detection
- Lower explosive limit measurements
- Arson investigation
- Indoor air quality
- Cleanroom facility maintenance
