PID
A PID (Photoionization Detector) sensor is a gas detector used to measure volatile organic compounds (VOCs) and other gases in the air. It operates based on the principle of photoionization, where gas molecules are ionized by ultraviolet light, producing positive ions and electrons. The sensor detects the generated ions and measures the resulting current, which is proportional to the concentration of the target gas.
PID sensors have high sensitivity and can detect a wide range of VOCs, making them valuable in industrial environments, environmental monitoring, and safety applications. They are commonly used in industries such as chemical manufacturing, petrochemicals, environmental protection, and emergency response. PID sensors provide real-time measurements and can detect gases at low concentrations, making them highly effective for identifying potential hazardous substances in various environments.
