Product details

Product Overview:

The hardness of water refers to the concentration of calcium and magnesium ions in water, calculated from the concentration of EDTA standard solution cEDTA and the consumed volume V1 (mL). Calculated as CaO or CaCO3, in mg/L.

The WTF2000 Hard hardness online water quality analyzer adopts complexometric titration method for analysis, with a detection range standard of 0-500mg/L, which 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.


Product features:

Using EDTA complexometric titration method for analysis, the titration volume is accurate to 10 μ L;

The core detection component is an imported brand, which can accurately determine the titration endpoint;

When the titration reaches the endpoint, the titration pump automatically stops working to save reagents;

The quantitative analysis module adopts a small-scale design approach, which saves reagents and reduces maintenance workload;

Running dynamic visualization, intuitive and convenient;

Over range upper and lower limit alarm, fault alarm;

Remote reading and writing of data, supporting remote calibration and correction;

The software adopts graded password management to ensure safe use;

The instrument is equipped with automatic cleaning and calibration functions;

Reserve external interfaces and customize extension functions according to on-site conditions;
