Principle
The detector adopts the principle of PID photoionization detection, and detects VOC gas by diffusion Sampling method. When the gas enters the detector, the PID Sensor detects the gas concentration through the photoionization process, and transmits the signal to the MCU chip for processing and output.
Applications
Industrial environment monitoring, workplace safety monitoring, Hazardous area Gas detection, environment monitoring system
