PH8012型工业复合污水PH电极
PH电极基本原理
PH测量中使用的电极又称为原电池。原电池是一个系统，它的作用是使化学能量转成为电能。此电池的电压被称为电动势（EMF）。此电动势(EMF)由二个半电池构成。其中一个半电池称作测量电池，它的电位与特定的离子活度有关；另一个半电池为参比半电池，通常称作参比电极，它一般是与测量溶液相通，并且与测量仪表相连。

PH8012 industrial composite sewage PH electrode
The basic principle of PH electrode
PH measurement is used in the electrode is also known as the primary battery. Primary battery is a system, it is the role of the chemical energy into electrical energy. The battery voltage is called electromotive force ( EMF ). The electromotive force ( EMF ) consists of 2.5 batteries. Among the 1.5 cell called the measuring cell, its potential and specific ion activity; the other 1.5 battery as the reference half cell, often referred to as a reference electrode, it is generally associated with the measurement of solution are communicated, and measuring instrument.
