ASP500 Online pH Sensor Designed for Pure Water

pH is one of the important indicators for water quality monitoring. Different solutions have different requirements for pH electrodes. Pure water is a liquid that is used in many industries. Examples include the pharmaceutical industry and biotechnology, the manufacture of electrical components, the field of semiconductor production, the food and beverage industry. In the field of energy production, power generation and petrochemical industry, pure water or ultrapure water is used as circulating water for boiler water supply, cooling system, etc. So what kind of pH electrode is suitable for use in the pure water industry?

In the pure water industry, pH electrodes are required to be made of high-purity materials. Since pure water requires extremely low ion concentrations, pH sensors must have low ion release characteristics. During the treatment of pure water, the change of pH is usually small and fast, so the pH electrode needs to have a fast response time, so that the change of pH value can be captured in time. The ultrapure water process also has very high requirements on the accuracy and stability of the electrode. The cleaning and maintenance of the pH electrode is also very strict.

Daruifuno's ASP500N online PH Sensor is specially designed for pure water. It uses low-impedance hemispherical glass membrane, high strength, not easy to break, and made of high-quality glass. The reference system is a double-salt bridge design. The reference adopts a large-area annular porous tetrafluoromembrane. The reference electrode is Ag/AgCl, filled with KCl colorless high-temperature gel, and has a fast response. In addition, in order to avoid the interference of pure water, especially Being a power plant, this pH sensor also comes with a stainless steel solution ground. In order to reduce cleaning and maintenance for customers, the pH electrode can be equipped with a cleaning joint to realize automatic cleaning function under water.

Features:
With stainless steel solution ground, designed for pure water environment
Double salt bridge design, annular ceramic hole, fast response, not easy to block
Built-in high-precision temperature resistance, fast response, timely temperature compensation
ABS or PPS plastic case package, with mounting threads at the beginning and end, easy to install

In short, the pH electrode of ultrapure water needs to have the characteristics of high-purity materials, low ion release, fast response time, high precision and stability. Selecting a special pH sensor that meets these requirements can effectively meet the needs of ultrapure water process for pH measurement and ensure the control of its quality and purity. We also provide the matched SG pH controller.
