Desulfurization of pH measurement of pH electrode is used for flue
gas desulfurization,the electrode adopts the gel electrode, free maintenance,
electrode under high temperature or high pH can still maintain high precision.
The basic principle of PH electrode
For measurement of the pH electrode is also known as Primary battery. Primary battery is a system; its role is to make the chemical energy
into electricity.The battery voltage is called the electromotive force (EMF). The electromotive force (EMF) consists of two half cell. One and
a half cell called measuring battery, its potential is associated with specific ion activity; another one and a half in reference battery, often referred
to as the reference electrode, it is general and measuring solution are interlinked, and connected to the measuring instrument. PH electrode made
by plane glass ball bubble, high pollution resistance and resistant to impact.

What is pH?
pH is a measure of the hydrogen ion activity in a solution. Pure water that contains an equal balance of positive hydrogen ions (H +)
and negative hydroxide ions (OH -) has a neutral pH.
● Solutions with a higher concentration of hydrogen ions (H +) than pure water are acidic and have a pH less than 7.
● Solutions with a higher concentration of hydroxide ions (OH -) than water are basic (alkaline) and have a pH greater than 7.
