Products Description
4S-NO2 sensor is a constant potential electrolytic nitrogen dioxide sensor. NO2 and O2 undergo corresponding REDOX reactions at the working electrode and the opposite electrode and release charge to form a current. The current is proportional to the concentration of NO2. The concentration of nitrogen dioxide gas can be determined by measuring the current.
Features
Low power consumption and high precision High sensitivity and wide linear range Excellent repeatability and stability
Applications:
Widely suitable for industrial field NO2 gas detection
