pH and ORP (Redox) combined electrodes without Liquid Junction. (pH und ORP Einstabmessketten Ohne Diaphragma) Refex is a Hard – Non-Porous – Ionically Conductive Polymeric interface/junction – that has made all porous/open/leaking reference electrodes obsolete. The polymeric material doubles as an immobilized electrolyte – and more importantly as a protective barrier that separates the process waters from the electrode’s internal Ag/AgCl reference half cell in 2.8 mol/l KCl electrolyte. No Exchange / contact of liquids (process with Ag/AgCl half cell/ electrolyte)

Advantages of Refex:

Cannot be fouled ( coatings must remain wet and conductive )
