Portable Water Quality Analyzer / Water Quality Hardness Analyzer / Water Quality Hardness Tester / Water Quality Hardness Tester Model: SX1-YD300
Water hardness refers to the total concentration of calcium and magnesium ions in the water sample, it is an important indicator of water quality. The instrument is tested by the electrode method. It has been proved by a large number of experiments that it has the same accuracy as the EDTA volumetric titration method, and can avoid many shortcomings of the EDTA titration method, such as troublesome operation, uncertainty of endpoint judgment, and unsuitability for turbidity And used in colored water samples.
The instrument has a built-in microprocessor chip, which is beautiful in appearance and easy to use.
