Electrochemical H2S Sensor MEu-H2S

Summary:

MEu-H₂S hydrogen sulfide gas sensor is a constant-potential electrolytic sensor. Hydrogen sulfide and oxygen 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 hydrogen sulfide concentration. Can determine the level of hydrogen sulfide concentration.

Feature:

* Excellent repeatability and stability

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.
