The TDS-3-W Tier1 TDS Water Test Meter is the perfect tool for measuring and tracking your waters levels of TDS to make sure your water filter is doing its job. With this meter, you won't just need to take the filter manufacturer's word that it reduces TDS in your water; you can put it to the test!

Total dissolved solids (TDS) are the total weight of all solids (minerals, salts, metals) that are dissolved in a given volume of water. The lower the TDS level in the water, the more efficiently your bodys cells can use the water. Conversely, higher TDS levels can indicate water that is more difficult for your body to use and has more contaminants that can pose health risks.

This meter is factory calibrated with dual range measurement and a 10 minute auto-shutoff to conserve battery life. Features a hold function that saves measurements for convenient reading and recording. Order the TDS-3-W Tier1 TDS Water Test Meter today!
