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.

Usage
-
Connect Chloride Ion Sensor to any port in SenseDisc.
Connect electrode to Chloride Ion Sensor.
Immerse the electrode into solution to collect data.
Typical experiment
Detect concentration of chloridion in tap water.
-
The change of concentration of chloridion in solution for manganese dioxide and concentrated hydrochloric acid reaction.
Note
-
To maximize the service life and best function, it is suggested that preserve the electrode in fridge and temperature around 5ºC.
-
Keep the plug of electrode dry and clean. Try to avoid corrosion and contamination occur on it.
-
Try to avoid friction and strong vibration occur on electrode during using.
-
Do not dry the electrode using gauze or tissue. It may damage sensing membrane.
