Product Description

Basic Principle of pH Electrode

In pH measurement, the used electrode is also known as the primary battery. The primary battery is a system, whose role is to transfer chemical energy into electrical energy. The voltage of the battery is called the electromotive force (EMF). This electromotive force (EMF) is composed of two half-batteries. One half-battery is called the measuring electrode, and its potential is related to the specific ion activity; the other half-battery is the reference battery, often called the reference electrode, which is generally interlinked with the measurement solution, and connected to the measuring instrument.

Features of ORP

It adopts the world-class solid dielectric and a large area of PTFE liquid for junction, difficult to block and easy to maintain.

Long-distance reference diffusion channel greatly extends the service life of electrodes in the harsh environment.

There is no need for additional dielectric and there is a little amount of maintenance.

High accuracy, fast response and good repeat-ability.
