Online water hardness tester, fixed hardness monitoring instrument

Measuring principle

Use a peristaltic pump to extract the sample into a titration cup, add ammonia ammonium chloride buffer solution and copper ion solution, and accurately titrate EDTA standard solution with a plunger pump. Calcium and magnesium ions are complexed by EDTA titration, and the titration endpoint is automatically determined by the potential change of the copper ion electrode. It has automatic cleaning and calibration functions.

This method is less susceptible to interference from turbidity, chromaticity, and other ions. Especially suitable for pre membrane monitoring in membrane wastewater treatment, it can effectively protect the lifespan of the membrane.
