With the Tier1 TDS-3-W meter, measuring the TDS levels in your water is easy. Perfect for testing to see if your water is suitable for drinking or for keeping your water filter honest.

TDS stands for Total Dissolved Solids and indicates the total weight of all solids (minerals, metals, salts) that are dissolved in the water. Generally, the lower the TDS level in the water, the easier it is for your body to use that water for hydration. The higher the TDS level, however, the more difficult the water may be for your body to use as well as the more contaminants it may contain.

This TDS meter features a hold function that saves measurements for future reading and recording as well as a 10 minute auto-shutoff to conserve batteries. Factory calibrated and simple to use. Order today!
