TDS (Tatal dissolved solids) Test pen is used to determine the sum of the inorganic soluble organic components such as anions and cations in water.
The number displayed on the TDS test pen is the amount of substance that is dissolved in water in an ionic state. TDS test pen used to test the water TDS value, the conductivity of water to determine the purity of water.

△ Water contains dissolved solids is very small, generally only zero to tens of milligrams / liter or so. Measured distilled water or pure water, TDS Tester shows a value of 0, which does not mean that TDS is broken, but that the water does not contain soluble substances.
△ If the measured water is more pure, the smaller the value displayed on the TDS test pen during measurement, the less the inorganic compound and the impurity composition contained in the water.
△ And mineral drinking water (filtered drinking water) contains a lot of mineral elements, so the value of TDS will be larger.

△ Factors that affect the TDS value test:
Water temperature: TDS pen can not be used to measure high temperature water (eg hot water)
Water flow rate: TDS pen can not be used to measure the shaking of large water bodies
Water pollution: TDS pen can not be used to measure the high concentration of water pollution
