These Thermo Scientific® Orion™ electrodes (PH4294-1/-2SC) combine a platinum redox and a silver/silver chloride reference electrode in one body. PH4294-1/-SC has a glass body with a ceramic junction and PH4294-2/-2BN is an epoxy body electrode with a sleeve junction. Both can be used to make direct measurements of redox potentials or to perform potentiometric titrations. They are not designed for amperometric or constant current titrations, such as the Karl Fischer. Recommended for measurement of reduction/oxidation potential and Redox titrations.
