SenseDisc Chlorine Gas

The working principle of Chlorine Gas Sensor is measuring concentration of chlorine 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 chlorine gas. Sensor converts the signal in electrode into analog signal.

Typical experiment

Generate chlorine gas by heating manganese dioxide and concentrated hydrochloric acid.
