Principle Introduction
| MEWOI-MIX8416 is an electrochemical hydrogen sulfide (H2S) sensor developed by Mixsen. It uses the principle of electrochemistry, the hydrogen sulfide gas undergoes a redox reaction under the catalyst condition. This produces the electric current. The current is directly proportional to the concentration of hydrogen sulfide . Through measure the current to get the concentration of hydrogen sulfide |
