TDS Water Quality Test Pen Digital Meter Filter Purity Measurement Temperature Instruments Tester
TDS is the abbreviation of English total dissolved solids, the Chinese translation for the total dissolved solids, measured in milligrams / liter (mg / L), which indicates that 1 liter of water which contains dissolved solids in milligrams.
TDS concept is an exotic, widely used in the US and Taiwan water treatment field, TDS value of the measurement tool is generally used TDS pen, the measurement principle is actually measured by measuring the conductivity of water to indirectly reflect the TDS value. In the physical sense, the more water dissolved, the greater the TDS value of water, the better the conductivity of water, the greater the conductivity value.
Popularity: TDS value represents the content of dissolved matter in water. The larger the TDS value, the greater the impurity content in the water, whereas the impurity content is small.
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 shaking large water bodies
Product manual:
Remove the pen holder and turn on the ON switch;
The pen into the test solution, the solution height of not more than 2cm;
The pen will be stirred in the solution, to be stable (2-6 seconds), the TDS value will be displayed on the screen, then press the HOLD key to lock the value.
After use, wipe the water on the pen, clean with pure water, the pen cover can be back.
Precautions: Avoid the TDS pen body soaked into the water, to avoid direct sunlight, away from high temperature, to avoid the impact of heavy pressure and fall touch.
Product use:
Detection of tap water, purified water, mineral water quality is consistent with drinking water standards: tap water 300PPM the following, pure water 50PPM the following, between 100-200PPM mineral water.
Test pen specifications are as follows:
● lightweight pocket weight of 28 grams, the smallest market for today's market, the lightest portable TDS instrument, length 14.2 × width 2.3 × thickness 1.3 (CM).
● Wide measurement range → can measure 1-9990PPM (display above 999PPM, the value to X10).
● Wide application temperature → work in 0-50 degrees, can be stored at minus 30 degrees.
● LCD display window → large screen LCD display waterproof design, easy to watch, durable
● long battery life → using LR44 battery 2, can be used for more than 3 years, 10 minutes does not operate the automatic shutdown function, saving the battery.
● design is reasonable → pen end electrode can be directly inserted into the measured water solution, pen can also be used as a container of water to be used to measure, very convenient.
● measurement fast → due to the delicate bare sensor components, 5 seconds to complete a measurement.
● Accuracy is high ± ± 1% error, titanium alloy probe water measurement accuracy, from the water interference in the water.
● Automatic temperature compensation → can automatically change the value of the display when the value of 25 degrees.
