65 G RO Filter Parts Manual Water Quality Tester TDS Meter Pen Blue



Description :


TDS pen measurement principle is actually measured by the conductivity of water to indirectly reflect the TDS value , from a physical sense , the more water dissolved in water , the greater the value of TDS , water conductivity is also better , the conductivity The greater the rate value .


TDS pen built-in battery , the pen has two long metal electrodes inserted in the water , due to the positive and negative electrodes formed between the high and low electric field , resulting in the ions in the water in accordance with a certain direction of the electric field to move . The formation of the current , resulting in the TDS pen on the LCD display a certain value , the greater the value that the water impurities and conductive ions the more . So the factors that affect the level of TDS values are the following aspects :

1 . The amount of impurities in water ;
2 . Water temperature (the higher the temperature, the stronger the ion activity) ;
3 . The difference between the height of the electric field in the water body (can replace the TDS pen battery verification) ;
4 . Water flow rate .

As a result of the installation of ultrafiltration or ceramic water purifier , after these two filter after filtration of substances such as colloid , sediment , rust and other greatly reduced , and ultrafiltration and ceramic filter can not afford to filter out the basic number of conductive ions remain unchanged . But the impurities mixed with them become less , therefore , the conductive ion activity becomes stronger . Ion activity becomes stronger , move faster , the current will become larger , resulting in higher TDS value .
