Electrochemical SO2 Sensor ME3-SO2

Summary:

ME3-SO₂ electrochemical sensor detect gas concentration by measuring current based on the electrochemical principle, which utilizes the electrochemical oxidation process of target gas on the working electrode inside the electrolytic cell, the current produced in electrochemical reaction of the target gas are in direct proportion with its concentration while following Faraday law, then concentration of the gas could be get by measuring value of current.

Feature:

* Low consumption

* High precision

* High sensitivity

* Wide linear range

* Good 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.
