The mixed solution is continuously stirred to ensure that the reaction proceeds fully. During the titration process, the hydrogen ions in the water sample are gradually neutralized, and the color of the phenolphthalein indicator begins to change from colorless to pink. When the titration endpoint is reached, that is, the hydrogen ions in the water sample are completely neutralized, the color change of the phenolphthalein indicator reaches a stable pink state. The instrument automatically stops titration and records the volume of alkaline solution consumed for calculating the phenolphthalein acidity in the water sample.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePerformance parameters\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"border-collapse: collapse; width: 100%;\" cellspacing=\"0\" cellpadding=\"8\" border=\"1\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f5f5f5;\"\u003e\n\u003cth\u003eTechnical Specifications\u003c\/th\u003e\n\u003cth\u003eParameter Values\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Method\u003c\/td\u003e\n\u003ctd\u003eNational Standard Titration Method\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExecution Standard\u003c\/td\u003e\n\u003ctd\u003eGB\/T 9736-2008, GB\/T 258-2016, GB 5009.239-2016\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Range\u003c\/td\u003e\n\u003ctd\u003e0.00 mmol\/L ~ 10.00 mmol\/L (range customizable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Period\u003c\/td\u003e\n\u003ctd\u003e15 minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrecision\u003c\/td\u003e\n\u003ctd\u003e≤5% F.S.
