pH Electrode for High Pressure

The pH glass electrode can be widely used for wastewater treatment, pure water industry, laboratory, etc.

Function:

• Malleable ring type PTFE protection diaphragm can prevent measurement media deposition and blockage.
• Shell material is high tenacity glass, high temperature resistant, high pressure resistant.
• Solid reserve salt ring design for low ion concentration or high flow rate environment.
• PH electrode adopts Germany Cartridge-style conducting system, free of silver ions, better stability.
• PC protection cover can storage saturated KCL solution to keep the electrode active.
• 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 pH electrode?
An industrial on-line pH measuring system generally consists of four parts, pH electrode (pH sensor), pH meter (pH transmitter), electrode sheath and cable. A pH electrode is a part of the pH meter contacting with measured substance. It's used to measure the electrode potential. Generally, there are two methods to measure the pH value of the aqueous solutions, namely Colorimetry (pH test paper and cuvette) and potentiometric method. The latter is the only way to realize continuous on-line measurement and process monitoring. Moreover, it can obtain accurate and repeatable pH value. The electrode used in the potentiometric method is called as primary battery, which is a system used to converse the chemical reaction energy into electrical energy, voltage of the primary battery is called for electrodynamic force (EMF). EMF consists of two half-cells, one of the half-cell is called for measuring electrode, whose potential is related to specific ionic activity. Another is a reference half-cell, which is also generally called for reference electrode, it generally communicates with measured solutions and connects with the measuring instrument.
