Electrochemical NO2 Sensor 4S-CL2

Summary:

The 4S-CL₂ sensor is a constant potential electrolytic chlorine sensor. Cl₂ and O₂ undergo corresponding redox reactions at the working electrode and the counter electrode and release charges to form a current. The current is proportional to the H₂S concentration. The chlorine concentration can be determined by testing the current.

Feature:

* Low power consumption
* High precision and sensitivity
* Wide linear range
* Strong anti-interference ability
* Excellent repeatability and stability

APPLICATION

Industrial Exhaust Monitoring

Industrial waste gas refers to the general term for various pollutant-containing gases discharged into the air generated during the fuel combustion and production process in the factory area of the enterprise. These gases enter the human body through the respiratory tract through different routes, some directly cause harm, and some have an accumulation effect, which will seriously endanger human health.
