PH meter electrode

1. Basic structure and principle

PH meter electrode is the most critical component of the PH meter, and its structure is precisely designed. It is generally composed of glass membrane, reference electrode, internal reference solution and other parts. The glass membrane is the part that is in direct contact with the measured solution, and it has a selective response to hydrogen ions. The reference electrode provides a stable potential reference, and the internal reference solution ensures the stability of the chemical environment inside the electrode. Its working principle is based on the Nernst equation. When the hydrogen ion concentration on both sides of the glass membrane is different, a potential difference will be generated. By measuring this potential difference, the pH value of the solution can be obtained.

2. Product characteristics

High-precision measurement

The electrode has extremely high measurement accuracy and can be accurate to two decimal places or more. Whether it is for precise pH determination of chemical reagents in the laboratory or monitoring the pH of the reaction solution in the industrial production process, it can provide reliable data.

Wide adaptability

It can adapt to many different types of solutions, including acidic, alkaline and neutral solutions. Whether it is a strong acid and strong base environment or a weak electrolyte solution, it can accurately measure the pH value. Moreover, it has a certain adaptability to different ionic strengths and temperatures, and can work normally in a wide temperature range (usually 0 - 60℃).

Fast response

When the electrode is immersed in the measured solution, it can quickly reach equilibrium and give a stable pH measurement value. This feature is very important in application scenarios where measurement results need to be obtained quickly, such as online real-time monitoring of pH changes in industrial processes.

3. Durability

High-quality materials

The glass membrane of the electrode adopts a special glass formula, which has good chemical stability and mechanical strength and is not easily corroded and damaged. Components such as the reference electrode and the housing are also made of corrosion-resistant materials to extend the service life of the electrode.

Low maintenance requirements

Under normal use, only simple cleaning and calibration are required regularly. Cleaning can remove dirt and impurities on the surface of the electrode, and calibration ensures the accuracy of the measurement. This low maintenance feature reduces the cost of use.

4. Application scope

Laboratory research

In chemical, biological, and medical laboratories, it is widely used to determine the pH value of various solutions, providing accurate data support for scientific research.

Industrial production

In the chemical, food, beverage, water treatment and other industrial fields, it is used to monitor the pH value in the production process to ensure product quality and the normal operation of the production process.

PH meter electrode has become an indispensable and important product in the field of pH measurement due to its high accuracy, wide adaptability, fast response, durability and low maintenance requirements.
