Shanghai Sanxin Precision pH Meter has become a domestically produced pH meter selected for the new standard validation report

1986In, China promulgated the first water quality regulationpHDetermination of Value The Glass Electrode Method ", time flies,30Over the years, with the vigorous development of China's economy and people's livelihood, this regulation was recognized by relevant departments many years ago and cannot meet the needs of environmental protection in China.2017In the year, the Office of the Ministry of Environmental Protection issued a revision notice. go through3After years of professional argumentation, research, and experimental verification, finally2020year11moon26Recently, the Ministry of Ecology and Environment of China released the "National Environmental Protection Standards of the People's Republic of China", also known as the "Water Quality Standards"pHDetermination of Value The "Electrode Law" and its establishment2021year6moon1Starting from the day of implementation.

The new national standard hits the industry's weak spot, outlines the direction, and points out the development direction of the electrochemical industry

2020Version of 'Water Quality'pHThe changes made to the electrode method for measuring values involve three major aspects:1. pHTesting theory and operational standards;2. pHTesting instrument function;3. pHSelection of electrodes. Shanghai Sanxin will break down the updates of the new national standard for you one by one. The updated content is highly targeted and operableIt has great practical guidance significance. It can be explained from three main aspects.

1. The new national standard includes5Article aboutpHThe content of theoretical updates and operational norms, forpHThe definition, preparation of standard buffer solution and standard values, sampling regulations (sampling bottle material, sampling process and time), etc. have been clearly defined and described, reflecting theoretical progress and clarifying operational norms.

2. have6Article aboutpHThe content of the instrument, such as specifying the reading stability standards, accuracy, and precision of the instrument, also requires functions such as automatic calibration and automatic temperature compensation. In fact, most of these functions in our countrypHThe instrument was already available many years ago. So this6The regulations regarding instruments are forpHThe clarification and summary of the current situation of the instrument have little impact on the industry.

These three short points highlightpHThe key issues of measurement require domestic electrochemical instrument manufacturers and indicate the development direction of the industry.

pHThe core technology and source of precision in measurement lie in electrodes

ifpHThe quality of the electrode is not strong enough, or the electrode is not suitable for the measured solution, even if the instrument's function is "high-end", it is of no help to the measurement results. Just as the key to the quality of photographic imaging lies in high-quality lenses (electrodes) that are suitable for the shooting scene, the role of the camera (instrument) is only to process the information captured by the lens in the subsequent process.

The formulation of the new national standard clearly indicates the importance of electrochemistry in ChinapHThe top priority of instrument development ispHElectrodes are developing towards technological innovation, functionalization, and customization. As required by the new national standard, use specialized equipment corresponding to differences in water qualitypHElectrodes require companies to develop various applicationspHElectrodes, such as strong acid resistant electrodes, strong alkali resistant electrodes, high salt resistant electrodes, low electrolyte electrodes, hydrofluoric acid resistant electrodes, and other special electrodes, meet the testing requirements of different industries and usage scenarios.

The validation report was prepared using the following methodspHFrom the statistics, it can be seen that Sanxin is one of the selected domestic brands for "Water Quality"pHThe electrode method for determining values is used in the new standard "Method Validation Report"pHCalculate.

The reason why Sanxin has been selected as a domestic instrument is probably due to the electrodes that come with the instrument.
