Online Nitrogen Dioxide Detector

The online nitrogen dioxide detector measures gas concentration using electrochemical or optical sensors and converts the signal into an electrical output. It is used to monitor nitrogen dioxide levels in industrial exhaust and ambient air, ensuring production safety and compliance with environmental standards.
Selection
When selecting, consider whether the detection range covers the application requirements, sensor lifespan and calibration intervals, whether the instrument's protection rating suits the installation environment, whether the output signal type matches the control system, as well as maintenance convenience and operational costs.
