The TDS-3-W Tier1 TDS Water Test Meter is a convenient portable TDS measurement tool that enables you to gauge whether your filter is performing properly. TDS stands for Total Dissolved Solids, this is the measurement in total weight of the solids such as minerals, salts, and metals that are present in your water. A general guideline is that the lower the level of TDS, the more efficient your body can use the water. This test meter features a auto shut off feature after 10 minutes to conserve battery life, and a hold function that allows you to save a measurement for convenient reading and recording. Give yourself the peace of mind knowing that you can validate the claims the filter companies are making with your own TDS meter.
