pH Glass Electrode for High Pressure

The pH glass electrode is made of high-quality pure copper wire, with a diameter of 4.5mm, strong anti-interference ability, and can achieve 60M transmission at the farthest. A high-pressure pH electrode has a built-in thermal conductivity medium, and the reference electrode is stable, which greatly improves the electrode response speed and stability.

High pressure pH electrode

High anti-interference and good stability

  • Malleable ring-type PTFE protection diaphragm can prevent measurement media deposition and blockage.
  • The 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 a Germany Cartridge-style conducting system, free of silver ions, with better stability.
  • PC protection cover can store 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.

 

Application

pH Electrode is widely used in the continuous testing and monitoring of pH, ORP, and temperature in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food, drinking water, etc.

FAQs

Q1: What is a pH electrode?
A1: The pH electrode is also called the pH probe pH sensor. The pH electrode is the part of the pH meter that is in contact with the substance to be measured and is used to measure the electrode potential.

Q2: Why do pH electrodes need to be soaked?
A2: The pH electrode must be soaked before use, because the pH bulb is a special glass membrane with a thin hydrated gel layer on the surface of the glass 
membrane, which can only interact with the H+ ions in the solution under fully wet conditions. the response to. At the same time, after soaking the glass 
electrode, the asymmetric potential can be greatly reduced and tend to be stable.

Q3: What is a reference electrode?
A3: An electrode with a known and constant electrode potential that does not respond to the activity of hydrogen ions in solution is called the reference electrode. Reference electrodes include mercurous sulfate electrodes, calomel electrodes, and silver/silver chloride electrodes. The most commonly used are calomel electrodes and silver/silver chloride electrodes. The role of the reference electrode in the measurement cell is to provide and maintain a  fixed reference potential, so the requirements for the reference electrode are that the potential is stable and reproducible, the temperature coefficient is small, and the polarization potential is small when current flows.

Tips: How to clean the electrode?

  1. Metal ions attached the measuring end of the electrode into 0.5 mol/I hydrochloric acid solution for 5 minutes, shake the electrode several times quickly (stirring) before taking it out, rinse with deionized water after taking it out, and soak in 3.0 mol/I potassium chloride solution for 4 hours.
  2. Contamination by organic matter
    Dip the measuring end of the electrode into anhydrous ethanol (or solvent capable of dissolving the organic material) for 15 minutes, shake the electrode rapidly (stirring) before removing, rinse with deionized water and soak in 3.0 mol/I potassium chloride solution for 4 hours. Note: The electrode shell material is polycarbonate, the organic sample or cleaning solution may corrode the electrode shell.
  3. 3. Inorganic cleaning
    Dip the measuring end of the electrode in 0.1mol/I EDTA solution or 0.1mol/l hydrochloric acid solution for 15 minutes, shake the electrode several times (stirring) quickly before taking out, rinse with deionized water after taking it out, and soak in 3.0mol/I potassium chloride solution for 4 hours.
  4. 4. Protein precipitation
    Soak the measuring end of the electrode in 1% hydrochloric acid solution of pepsin (concentration of hydrochloric acid is 0.1 mol/I) for 15 minutes, shake the electrode rapidly several times (stirring) before removing, rinse with deionized water after removing, soak in 3.0 mol/I potassium chloride solution for 4 hours.
  5. 5. Grease adhesion
    Immerse the measuring end of the electrode in a weak alkaline detergent for 15 minutes. After removal, rinse with deionized water and immerse in 3.0 mol/I potassium chloride solution for 4 hours.
  6. 6. Regeneration of the glass-sensitive film
    Soak the measuring end of the electrode in 4% hydrofluoric acid solution for 3-5 seconds, then rinse with 1:1 hydrochloric acid solution for 10 seconds. The hydrochloric acid solution was rinsed for 10 seconds, cleaned with distilled water, and stored in a 3.0 mol/I potassium chloride solution soaked for 24 hours.
