Combination pH electrode can be used for water sample with very low ionic strength, pure water industry, thermal power plant.

Function:

• Adopt ceramic sand core liquid junction, two-liquid junction electrode, effectively extends electrode service life.
• Shell material is special glass, high temperature resistant, acid and alkali resistant.
• The gel electrolyte does not require additional electrolyte.
• Accessories: PTFE sheath or stainless steel sheath. Increase the acid and alkali resistance of the electrode, easy to install.
• High-quality low-noise cable, can achieve 60m long distance signal transmission.

Specification:

Specification of sheaths (optional accessories):

The pH electrod installation methods:

1. Side wall installation (*The pH electrode must be at an angle of 15 degrees to the liquid surface. Otherwise, it will affect the normal use of the pH electrode.)
2. Flange mounted at the top
3. Pipe installation
4. Top installation
5. Submersible installation
6. Flow-through installation

Tips: What is a two-liquid junction reference electrode?
Two-liquid junction reference electrode consists of two liquid-junction borders and two reference solution chambers. The external chamber is generally contained with kno3 solution while the internal chamber is contained with kcl solution. It has two distinct advantages. Firstly, reduce pollution. The measured solution can only pollute the solution in the external chamber but has limited influence on the kcl solution in the internal chamber. Secondly, reduce the liquid-junction blockage and chemical reactions between ions. For example, the s-, i- ions in the measured solution may react with the ag+ in the reference solution, thus producing insoluble silver compounds to block the liquid-junction boarder. Two-liquid junction reference electrode is the calomel electrode. It is generally used for industrial pH electrode.
