Water Total Hardness Tester

The total water hardness tester uses the EDTA complexometric titration method, where calcium and magnesium ions combine with an indicator to produce a color. The color changes abruptly when the titration reaches the endpoint. It is used to measure the total amount of calcium and magnesium ions in water, monitor the scaling tendency of industrial water, and is suitable for hardness testing in boiler water, circulating cooling water, and other applications.
Selection
When selecting, consider the measurement range covering usage needs, accuracy meeting detection requirements, ease of operation, reagent shelf life, equipment maintenance costs, environmental adaptability, data output methods, and compliance with industry standards and regulations.
