ME4-NO2 Nitrogen Dioxide Gas Sensor 0 - 20ppm in Mine

Product Description
ME4-NO2 Nitrogen Dioxide Sensor 2 Years Life



ME4-NO2 sensor is a constant potential electrolytic NO2 sensor. The corresponding redox reaction between NO2 and O2 occurs on the working electrode and the counter electrode, and the charge is released to form a current. The magnitude of the generated current is proportional to the concentration of NO2. The concentration of NO2 can be determined by testing the magnitude of the current.
