NOX gas alarm

The NOX gas alarm detects the concentration of nitrogen oxides in the environment through an electrochemical sensor. When gas contacts the sensor, it generates a current signal, which is processed by the circuit to trigger audible and visual alarms. It is used for monitoring nitrogen oxide leaks in places such as printing workshops and chemical laboratories where combustion or chemical reactions occur, ensuring personnel safety.
Selection
When selecting, ensure that the detection range covers the actual application concentration, and electrochemical sensors require regular calibration. The explosion-proof rating must match the on-site environment, considering the effects of temperature and humidity. The output signal should be compatible with the existing control system, and the probe material must be corrosion-resistant. Review the sensor lifespan and calibration cycle to assess maintenance costs.
