WATER QUALITY METER

The meter is primarily used to indicate ZeroWater® filter 
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 
should not be used to assess the safety or purity of water, 
which should only be undertaken by a qualified laboratory.

For a more scientific 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.

METER INSTRUCTIONS

FOR WATER QUALITY METER:

Remove cap, turn on, submerge
