H2S Sensor
Classification： SenseDisc
Product Model：MAS 5474-S1031
Grade：Elementary school, junior high school, Senior high school
Function Description：
The working principle of H2S Sensor is measuring concentration of gas by using electrochemistry. The probe consists of electrode and electrolyte. The electrolyte is separated by a selective gas-permeable membrane. The gas diffusing in sensor occurs redox reaction on the surface of electrode. Current is generated in the electrode. The value of current is corresponding to the concentration of gas. Sensor converts the signal in electrode into analog signal.
