SenseDisc Chloride Ion

The sensor is designed with ion selective electrode. It is a kind of electrochemistry sensor which measures ion activity and concentration in solution using membrane potential. When it touches the solution with ion to be measured, membrane potential will be generated between its membrane and solution. Ion selective electrode is also called membrane electrode. There is a layer of special electrode membrane on the electrode which response to specific ion. The relationship between potential of electrode membrane and ion to be measured compliance with Nernst formula. The circuit of sensor convert potential to analog signal.

Typical experiment

Detect concentration of Chloride Ion in tap water.

The change of concentration of Chloride Ion in solution for manganese dioxide and concentrated hydrochloric acid reaction.
