Overview
4S-NO2 Electrochemical Nitrogen Dioxide Sensor
Product Details
product details
The 4S-NO2 sensor is a constant potential electrolytic typeNitrogen dioxide sensorNO2 and O2 undergo corresponding oxidation-reduction reactions at the working electrode and counter electrode, releasing charges to form a current. The magnitude of the current is proportional to the concentration of NO2, and the concentration of nitrogen dioxide gas can be determined by testing the magnitude of the current.
Sensor characteristics
Low power consumption, high precision, high sensitivity, wide linear range, strong anti-interference ability, excellent repeatability and stability.
Main applications
Widely suitable for the detection of NO2 gas in the industrial field.
