Water can look perfectly clear while still containing dissolved minerals, salts and other substances you cannot see.
A simple TDS test gives you a quick indication of the level of dissolved solids in your drinking water — in just a few seconds.
Curious about your own water? Test it for yourself.
It is a measurement of dissolved substances in water and is usually shown in parts per million — ppm.
These dissolved substances may include naturally occurring minerals, salts and other dissolved material.
Measured in PPM
Your TDS meter provides a simple numerical reading that allows you to compare different water sources.
Easy to Compare
Test your tap water, bottled water and purified water and compare the readings for yourself.
A Starting Point
A TDS reading does not identify individual contaminants, but it can help you understand how much dissolved material is in the water.

Test your own tap, bottled or filtered water and see what reading you get.
Electrolysis creates visible reactions between dissolved substances in the water and the electrodes used during the test.
The demonstration helps show that clear-looking water can still contain dissolved substances that are invisible to the eye.
A simple handheld TDS meter allows you to compare the level of dissolved solids in the water you drink every day.

Includes simple instructions to help you complete your first water test.
A TDS meter estimates the concentration of dissolved substances in water and displays the result in parts per million — ppm.
Not necessarily. TDS measures the overall amount of dissolved substances rather than identifying individual contaminants. Some dissolved minerals occur naturally and are not harmful.
