This test box is specifically designed for rapid and accurate detection of the pH value of acidic oxidizing water on site. According to GB28234-2016 "Safety and Health Standards for Acidic Oxidizing Water Generators" and the requirements of the "Disinfection Technical Specifications" of the Ministry of Health, effective chlorine can only have better disinfection effect at an appropriate pH, so the pH value of the disinfectant solution needs to be measured. This test box uses titration to determine the concentration of hydrogen ions in acidic oxidation potential water based on the principle that the indicator turns red under alkaline conditions, thereby obtaining the pH value of the acidified water. This method completely overcomes the disadvantages of difficulty in distinguishing the color of pH test paper and excessive detection deviation, avoiding the problem of inconsistent readings due to individual differences in color sensitivity. All reagents and accessories are built-in, and it takes 2-5 minutes to complete the analysis of a water sample accurately, quickly, and efficiently. Measurement range: 1-3
