ModBusRTUZONEWU's nitrogen dioxide sensor adopts imported first-line brand electrochemical nitrogen dioxide sensors, with fast response speed and strong anti-interference ability. After our company's unique compensation algorithm and gas calibration, the measurement is more accurate and stable. Monitoring NO ₂ emissions from chemical production, power generation, and automotive manufacturing plants is crucial in industrial environments. The nitrogen dioxide sensor adopts a wide voltage 10-30V DC power supply and has output modes such as RS485 and LoRa.
