Ion Selective Electrode for Chloride

Cl^-

Technical Data Sheet

Structure of the Electrode

range^*:

5 10^-5 to 1 mole chloride
1 to 35,000 mg/L chloride

The iRAS chloride selective electrode is an solid state membrane electrode. The chloride selective membrane is made from a highly pressed AgCl/Ag₂S sensor element embedded in a plastic shaft by means of a special resin.
A silver contact layer and a shielded cable is used for potential discharge.
