Online hardness water quality analyzerUsing complexometric titration analysis, the detection range standard is 0-500mg/L, and the range can be customized according to the actual water sample. The analyzer titrates EDTA standard reagent into the water sample until the solution changes from burgundy to pure blue, which is the endpoint of titration. The instrument automatically calculates the concentration of calcium and magnesium ions in the water sample based on the built-in curve; If there is a small amount of zinc ions in the water sample, β - aminoethanethiol needs to be added for masking.

Online hardness water quality analyzerProduct features:

Analyze using EDTA complexometric titration method, with a titration volume of 10 μ L;
