Measurement principle of TDS pen is actually by measuring the conductivity
of the water and thus indirectly reflect the TDS value from the physical
sense, more water, solutes, water TDS value is higher, the better the
conductivity of the water, it's conductivity the higher the rate. Does not
exist a linear relationship between the TDS value of the conductivity, the
actual measurement statistics show that approximately multiples of values
between them at the same time, the measured values of TDS pen is
about 1/2 of the conductivity measured values. Popular speakers, the
the TDS value on behalf of the water.
TDS pen dissolved impurities in the TDS value of the greater, indicating that
the impurities in the water content, on the contrary, impurity content. U.S.
drinking water standard is : ***0, European standard is a factor
of ***0. TDS value of the test: water temperature: TDS pen can not be used
to measure the high temperature water .( for example: hot water ) and high
flow rate water, and can't be used for measuring pollution higher concentration
of water. TDS pens: TDS ( Total Dissolved Solids ) is the total dissolved
solid matter in the water. It means 1/***0g (mg/L), or
1/******0 (PPM). Characteristics of the products: 1: Be able to lock the
test date ( Hold button), to automatically shut down after *0 minutes ,a wide range of
measurement: the ability to measure *****0PPM, high accuracy: ±2% error,
unique temperature compensation function to automatically converted into
TDS in the water temperature of *5℃: large-screen LCD
waterproof design for easy viewing durable, long time without frequent battery replacement.
Normal use for 2 years .
Factors affecting the TDS value of the test:
Water Temperature: the TDS pen can't be used to measure the high-temperature
water
Water flow rate: TDS pen can't be used to measure the shaking of a large
body of water
Water pollution: TDS pen can't be used to measure high
concentrations of pollution water
