Portable Digital TDS Meter Tester Water Quality Purity Measurement TDS-3
The LCD digital TDS meter tester is used for testing the filter water quality purity, to check the performance of your water.Versatile test for simultaneous temperature measurement
Digital TDS Meter Standards for testing water
- 0~50ppm ——— High Purity Water
- 50~100ppm ——— Pure Water
- 100~300ppm ——— General Pure Water
- 300~600ppm ——— The water will have incrustation scale
- 600~1000ppm ——— Bad Taste Water
- Above 1000ppm ——— The water is not suitable for drinking
Precautions:
- TDS test pen can not be used to measure high temperature water
- TDS test pen cannot be used to measure water bodies with large sloshing
Steps for usage:
- Take down the pen holder
- Press [ON/OFF] to turn on the power of the pen
- Insert the pen into the test solution to the water line position
- Gently stir to remove the bubbles in the pen
- Wait for 3 seconds to read stable, press [HOLD] to take the pen out and read the value.
- After use, wipe the water on the pen tip and cover the pen cover.
Total dissolved solids (TDS)
A measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form. TDS concentrations are often reported in parts per million (ppm). Water TDS concentrations can be determined using a digital meter.
Generally, the operational definition is that the solids must be small enough to survive filtration through a filter with 2-micrometer (nominal size, or smaller) pores. Total dissolved solids are normally discussed only for freshwater systems, as salinity includes some of the ions constituting the definition of TDS. The principal application of TDS is in the study of water quality for streams, rivers, and lakes. Although TDS is not generally considered a primary pollutant (e.g. it is not deemed to be associated with health effects), it is used as an indication of aesthetic characteristics of drinking water and as an aggregate indicator of the presence of a broad array of chemical contaminants.

Уже традиционно без элементов питания. Пластик кривой, держать не приятно. Индикатор плохо просматривается. Пока не понял, но ощущение что сам не отключается, но не проверял. Но если его воспринимать как дешевый-китайский, то прибор нормальный, работает хорошо, воду и градусы показывает. Так что бюджетненько но вполне сностно.
