What TDS readings can and cannot tell you

A number.
With context.

TDS helps compare samples. It does not determine drinking-water safety.

Display, buttons and cap of a handheld TDS meter

Simple details.
Everyday ease.

A digital display, physical controls and a protective cap.

Illustrative product guidance and support concept

Clarity you can
come back to.

TDS cannot establish drinking-water safety. The footage does not establish that tap water is unsafe. Product imagery and pictured service materials are illustrative.
