Product Description

PH Electrode Series
Product overview  
The principle of pH electrode measurement is electrochemical method and galvanic battery principle. The primary battery is a system whose function is to turn chemical energy into electrical energy. The voltage of this battery is called electromotive force (EMF) which is made up of 2 half-cells, of which one is called a measuring cell whose potential is related to specific ionic activity; the other is a reference half-cell, commonly known as a reference electrode, which is generally interlinked with the measuring solution and is connected to the measuring instrument. The potential difference produced by the galvanic interaction inside the electrode is transmitted to the pH controller, and the corresponding algorithm is transmitted to display the pH value.Application:

Applications
Sewage treatment plants:
Oxygen measurement and regulation in the activated sludge basin for a highly efficient biological cleaning process
Environmental protection water monitoring:
Oxygen measurement in rivers, lakes or seas as an indicator of the water quality
Water treatment:
Fish farming:
Oxygen measurement and regulation for optimum living and growth conditions
 

Measuring principle

PHW014




The PHW014 electrode consists of a pressure-resistant hemispherical pH-sensitive membrane, an intermediate dielectric composed of complex gum GMT, an Ag/AgCL/KCL external reference system, and an OPEN liquid junction without salt bridge, which is widely used in pure water and high purity water as well as complex chemical processes



PHW015




PHW015 electrode has large sensitive areas and is resistant to mechanical shock; it is widely used in various chemical processes including microbial technology, pharmaceuticals, food and beverages, sugar manufacturing, chlor-alkali, mining and smelting, paper pulp, textiles, petrochemical industry and semiconductor electronic industry as well as fields such as wastewater treatment.

PHW016



The PHW016 electrode can withstand high temperature above 150 ºCand can withstand strong acid and alkali corrosion, which is widely used in wastewater treatment and in the fields including mining and smelting, papermaking, paper pulp, textiles, petrochemical industry, process of semiconductor electronic industry, and downstream engineering of biotechnology



PHW017




The PHW017 electrode uses a cylindrical pH-sensitive membrane made of alkali-resistant glass by blowing. The external reference electrolyte system is composed of pre-charged gel PFT/GFT, which can withstand the osmotic pressure of up to 6 Bar. The electrode is widely used in various chemical processes including chlor-alkali, mining and smelting, papermaking, paper pulp, textiles,petrochemical industry and semiconductor electronic industry as well as fields such as biotechnology and wastewater treatment.
