Hardness online water quality analyzer
The hardness of water refers to the concentration of calcium and magnesium ions in water, which is calculated by the concentration of EDTA standard solution and the consumption volume V1 (ML). In terms of CaO or CaCO3, the unit is mg / L.
WTF2000 hard hardness on-line water quality analyzer adopts complexometric titration method for analysis, and the detection range standard is 0-500mg / L, which can be customized according to the actual water sample. The analyzer titrates EDTA standard reagent into water sample until the solution changes from wine red to pure blue. The instrument automatically calculates the concentration of calcium and magnesium ions in water samples according to the built-in curve; If there is a small amount of zinc ion in the water sample, it needs to be added β- Aminoethanethiol was used as masking agent.

·EDTA complexometric titration was used, and the titration volume was accurate to 10 μ L；
·The core detection component is imported brand, which can accurately determine the titration end point;
·When the titration reaches the end point, the titration pump will stop automatically to save reagent;
·The quantitative analysis module is designed with small specifications, which saves reagents and reduces maintenance workload;
·Dynamic visualization, intuitive and convenient operation;
·Over range upper and lower limit alarm, fault alarm;
·Remote read and write data, support remote calibration and calibration;
·The software adopts hierarchical password management to ensure safe use;
·The instrument is equipped with automatic cleaning function and automatic calibration function;
·The external interface is reserved, and the expansion function can be customized according to the site conditions;
