WHAT IS TDS?
Total Dissolved Solids (TDS) are the total amount
of mobile charged ions, including minerals, salts or
metals dissolved in a given volume of water. TDS,
which is based on conductivity, is expressed in parts
per million (ppm) or milligrams per liter (mg/L). TDS
includes any conductive inorganic element present
other than the pure water molecules (H
2
O) and
suspended solids.
TDS affects everything that consumes, lives in or uses
water, from fish and plants to plumbing and
laboratories.
For people, the lower the TDS level in the water you
drink, the more efficiently your body’s cells are
hydrated. The higher the TDS level in water, the
greater the probability of harmful contaminants that
can pose health risks or hinder the absorption of
water.
The U.S. EPA’s Maximum Contaminant Level of TDS
for human consumption is 500 ppm.
USE THE TDS-3 METER TO:
Check the performance of your water filter.
Be sure your drinking water is at the right TDS level.
Measure TDS levels for other applications.
