UNDERSTANDING THE TDS METER
The TDS meter helps you put a number on what your taste buds are already telling you
about what’s in your water. It measures for the things in water that can give it a taste.
The higher the reading on the water, the more substances dissolved in your water.
For a more scientifi c explanation, it is showing you the total number of detectable
dissolved solids in water. With the push of a button, the electrodes in the bottom
of the tester measure the amount of ions in the water and convert that amount
to a number that displays on the screen. The number represents the amounts of
detectable dissolved solids in parts per million that exist in your water sample.
The meter is primarily used to indicate ZeroWater
®
fi lter replacement at 006. It may
also be used as a simple method to compare water quality by displaying the Total of
the Dissolved Solids (TDS) in parts per million only. The meter does not specify what
substances comprise the Total. The meter should not be used to assess the safety or
purity of water, which should only be undertaken by a qualifi ed laboratory.
