In key fields such as food testing, biomedicine, and environmental monitoring, the accuracy of acidity meters directly determines experimental results and product safety. Nowadays, more and more research institutions are turning their attention to domestic strength - the acidity meter from Shanghai Sanxin Peirui Instrument Technology Co., Ltd. With its stable performance and professional quality, it has won the trust of research teams in many provinces and cities across the country, becoming a "standard artifact" in laboratories.

A reliable reputation stems from over thirty years of deep technical cultivation. Since its establishment in 1991, Sanxin Peirui has always focused on the field of electrochemical analysis, forming a professional R&D team to overcome multiple technical challenges. Its acidity meter is equipped with independently developed composite glass electrodes, a special membrane formula, and a reference system that enables measurement accuracy of ± 0.002pH, with a resolution as low as 0.001PH, far exceeding industry standards. For complex samples with high salt and high turbidity, the electrode is equipped with an anti pollution coating and an automatic temperature compensation function from -5 ℃ to 105 ℃ to ensure stable and reliable data.

The SX5150 acidity meter is used to monitor the concentration of regeneration solution in ion exchangers. It is an instrument for producing high-purity water by ion exchange method and can be applied to detect the concentrations of HCl, H2SO4, HNO3, HCl, NaOH, Na2CO3, NaCl, and KOH solutions in industries such as power, chemical, metallurgical, food, and pharmaceutical. The electrode method is used to measure the concentration of acid-base solutions. The ND800-S acid-base concentration electrode with a special structure is composed of a measuring electrode and a temperature electrode, which is corrosion-resistant and can be wiped and cleaned. It has a novel structure, fast response, and easy use. Compliant with international GLP requirements, it has intelligent functions such as automatic calibration, automatic temperature compensation, data storage, timed measurement, RS232 output, clock display, and function settings. By using digital filtering and slip technology, the response speed of the instrument and the accuracy of measurement data are intelligently improved, and a smiling face icon is displayed when the measurement value is stable. Large measurement range, one electrode can test the full range; Widely applicable, capable of measuring the concentration values of seven types of acid-base salt solutions.

From precision experiments in university laboratories to water quality analysis in environmental monitoring stations, Sanxin Peirui's application cases cover various fields. As a high-tech enterprise in Shanghai, its factory has passed ISO9001 quality management system certification. Its products not only serve domestic scientific research, but also export to multiple countries, occupying an important position in markets such as the United States and Europe.

The craftsmanship of "credit, trust, and belief" runs through every product of Sanxin Peirui. From core electrode research and development to full cycle service support, this enterprise is redefining the value of domestic instruments through technological innovation. When research institutions choose Sanxin Peirui one after another, it is not only a recognition of precision, but also a trust in domestic strength. Choosing Sanxin Peirui acidity meter ensures accurate and worry free measurements, laying a solid foundation for scientific research and innovation.
