The PQN Series Gas Detectors are advanced devices designed for the continuous measurement of toxic and explosive gases in hazardous areas. They are certified with ATEX/IECEx and SIL2, ensuring compliance with international safety standards. These detectors are equipped with ex-proof housing, providing safe operation in potentially dangerous environments. The devices are built to be robust and durable, featuring SS316 stainless steel sensor heads and IP65/IP66 protection ratings. They offer accurate readings using a variety of sensors, including Pellistor, Electrochemical, PID, and Infrared. The detectors are ready to operate with onboard 4-20mA Analog and Modbus RS485 RTU outputs, eliminating the need for additional setup. Easy maintenance is supported through pre-calibrated sensor heads and Procell technology. Optional relay modules allow for simple external equipment control, enabling two adjustable concentration alarms and one fault alarm. The detectors include a continuous self-test feature to ensure proper operation and generate fault signals if any issues arise. Adjustable parameters and automatic calibration via preset values in the detector software make them adaptable to various application requirements. They are suitable for applications such as Process Industry, Water Treatment, Chemical Industry, Food and Medicine Facilities, Metal Industry, Gas Distribution Stations, and Laboratories. The product is marketed as a reliable, safe, and versatile solution for gas detection in industrial and hazardous environments.
