Pocket TDS

Portable pocket TDS meters are ideal for measuring the total dissolved solids in water up to 9,990 ppm (see product details tab for specific model limits).

Pocket Meters' compact size makes them ideal for use on the go. Their economical prices make them suitable for use at home for checking tap water or RO permeate water TDS.

TDS Testing is fast and easy: Simply turn on the TDS meter, immerse it into the solution to be tested, stir gently, and wait for the reading to stabilize.
