About The System

Testing TDS has never been easier!

This easy to use hand-held digital monitor can test and monitor your water quality in Total Dissolved Solids (TDS).

It is used to test your water quality before and after the RO system. It allows you to stay on top of your drinking water quality at all times!

The TDS meter can also be used to monitor when it is time to change the membrane.
