There’s  not much point in owning a water purification system if the quality of the  water is not much better than that which comes straight out of the tap!

Test the TDS  [Total Dissolved Solids] content and monitor the performance of your filter or  membrane with this dual inline TDS meter which measures the tap water going in  against the purified water going out of your system.

The TDS  meter instantly displays the TDS levels of the water and is the ideal way to  tell if your reverse osmosis system is due for a service.

The TDS  meter accurately measures from 0 to 9990 ppm, includes all fittings and is  simple to install.
