Precision Electronic Portable TDS Water Testing Meter 65 G With
The use of principles and precautions :
1.The value of the TDS represents the amount of dissolved
impurities in the water .
2.TDS value larger , indicating that the water content of
impurities, on the contrary small impurity content .
TDS Tester is used to measure the total dissolved solids in water ,
a dedicated tester . Pure water contains dissolved total solids is
very small , only about zero to tens of milligrams per liter . If
the water is contaminated or has dissolved into many other
electrolytes , the total solid content increased . TDS tester can
be fast and convenient to directly measure the type of indicators .
Users in the course of the TDS tester as long as the test end into
the water being tested , TDS tester immediately put the water
dissolved in the foreign body content test and display it . In
other words , the number displayed on the TDS tester is the total
amount of the substance dissolved in the water .
Factors that affect TDS testing :
Water temperature : TDS can not be used to measure high temperature
liquid (for example: hot water)
Water flow rate : TDS can not be used to measure large swaying liquid
Instructions for use :
1 . Remove the pen cover , open the ON switch ;
2 . Put the pen into the test solution , the solution height should
not exceed 2cm ;
3 . The pen will stir in the solution until the reading is stable
(2-6 seconds) , TDS value will be displayed on the screen , then
press the HOLD key to lock the value .
4 . After using the dry wipe the water on the head , with clean
water clean, cover the pen can be back .
Avoid soaking the TDS pen into the water , avoid direct sunlight ,
away from high temperature , avoid impact and weight .
Product range :
Detection of tap water , purified water , mineral water , water
quality is in line with the state to develop drinking water
standards : water 300PPM below , pure water 50PPM (national
standard) , mineral water 100-200PPM between .
