Overview
The pH glass electrode is used for high-temperature, sterilized measurements. The dual liquid connection structure of the high-temperature-resistant gel and high-temperature-resistant solid dielectric allows the glass electrode to be sterilized directly at a temperature of 130 degrees Celsius.

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: What types of pH electrodes are there?
Liquid pH Electrode
The liquid electrode is a filled liquid electrode, which is the most typical, excellent quality, and most widely used electrode in the history of pH electrodes. Suitable for measurement of various industrial processes.
Gel pH Electrode
Gel electrodes are improved liquid electrodes. This electrode requires little maintenance and is suitable for demanding in-line measurements. It can still work for a long time after many times of CIP (cleaning in place) and SIP (steam sterilization).
Solid pH Electrode
Solid electrodes are widely used in the chemical industry. Features a new solid polymer reference electrolyte for extended life while maintaining accurate pH measurements for good performance even in the harshest industrial environments.
