The Pt4865 probe is a redox version of the 465-50 electrode. It is a liquid electrolyte-filled electrode and is designed for conducting in-line oxidation-reduction potential (ORP) measurements in biotechnology applications. The Friscolyte-B reference liquid electrolyte is suitable for conducting measurements in all biotechnology applications, as it effectively prevents protein precipitation on the diaphragm. The electrode is equipped with a patented silver ion trap, this prevents the precipitation of silver sulfide deposits on the diaphragm when the electrode is in contact with a medium containing sulfides. This solution makes it possible to significantly extend the life of the electrode. This electrolyte-filled electrode is particularly dedicated to installation in tanks with pressures of up to 6 bar.

Pt4805 gel redox electrode with low maintenance requirements for use in chemical applications. The Pt4805-DPA electrode is filled with a pressurized gel electrolyte. It is specifically designed for in-line oxidation-reduction potential (ORP) measurements in chemical applications. It is dedicated for use in reactors, tanks, open pools and transmission lines - wherever there are particularly harsh process conditions due to the chemical composition of the medium under test.
