MG832 Nitrogen Dioxide Solid Electrolyte Gas Sensor
Product details
product details
MG-832 is a semiconductor oxide chemical sensor that uses the principle of solid electrolyte battery to detect NO2. When the sensor is maintained at a certain working temperature and placed in an NO2 atmosphere, electrode reactions occur between the positive and negative electrodes of the battery. An electromotive force is generated between the sensitive electrode and the reference electrode of the sensor, and the output signal voltage is inversely proportional to the logarithm of the NO2 concentration. By testing the change in signal voltage, the change in NO2 concentration can be detected.
Sensor characteristics
MG-832 gas sensor has a small volume, low power consumption, high sensitivity and good selectivity to NO2, and is less affected by temperature and humidity changes. The sensor signal has good stability and repeatability.
Main applications
Used in the fields of industry, agriculture, mining, warehousing, and environmental protection for detecting oxygen concentration.
