Photoionization Detector (PID)
|
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 a highly accurate, efficient and inexpensive detector for many gas and vapor concentrations. PIDs produce instantaneous readings, operate continuously, and are commonly used as fixed and 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
