2 in 1 pH ORP sensor electrode probe
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) iscomposed of two half-batteries.
One halfbattery 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.
