Combination pH electrode can be used for water sample with very low ionic strength, pure water industry, thermal power plant.Function:
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 top3. Pipe installation4. Top installation5. Submersible installation6. 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.
