The Nexisense GTYQ-MIC-300-PID is a fixed PID gas detector that uses advanced PhotoIonizationDetection (PID) technology to monitor various Volatile Organic Compounds (VOCs) such as Benzene,Toluene, Xylene, Ammonia, and TVOCs. The device offers high precision, rapid response, and strong anti-interference capabilities, making it suitable for hazardous environments in industries such as petroleum and chemical, paintingworkshops, pharmaceuticals, electronics manufacturing, and logistics.

Working Principle of PID(Photo Ionization Detector)

The Nexisense GTYQ-MIC-300-PID utilizes a UV light source to ionize gas molecules, creating positive and negative ions. The detector thenmeasures the resulting current to determine the gas concentration. Compared to traditional electrochemical or catalytic combustion sensors, the PID sensor offers several advantages:

• High sensitivity to low concentration VOC gases,capable of detecting at ppb levels;

• Fast response time (T90 ≤ 20s);

• Not affected by oxygen concentration, suitable for complex environments;

• Sensor light tube can be replaced to adjust the detection range.
