The equipment automatically quantifies the sample by adding reagents to the measuring tank through a precision measuring device for titration. The reagents react with the calcium ions in the sample, causing a change in the color of the solution. Optical sensors are used to detect the intensity of the color and determine the endpoint of the color change. Based on the amount of reagents consumed, the concentration of calcium ions in the water sample can be determined, thereby obtaining the calcium hardness of the water quality.\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 6909-2008\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Range\u003c\/td\u003e\n\u003ctd\u003e0.00~1000.00 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Period\u003c\/td\u003e\n\u003ctd\u003e≤15 minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrecision\u003c\/td\u003e\n\u003ctd\u003e≤5% F.S.
