iSpring TDS 3-Button Digital Water Quality Test Meter


TDS meters (also known as ppm pens, nutrient testers, and TDS sticks) are inexpensive and convenient digital tools for instant verification of total water quality. TDS stands for total dissolved solids, which are salts, minerals, or minerals in the water. With the push of a button, the TDS meter tells you the general purity level of your water, displayed on the screen in parts per million (ppm). The lower the TDS value, the purer the water will be 0 ppm of pure H2O.

TDS meters are great for checking the quality of tap water and knowing when to change your filter. TDS meters are great tools for drinking water, water filtration and purification, colloidal silver, hydroponics (nutrient testing), aquariums, RO/DI systems, pools and spas, commercial and industrial applications, and more. The TDS meter is a rugged model with a protective carrying case. Press the temperature button to test the water temperature (wait a minute or two for an accurate temperature compensation reading).

Total dissolved solids, also known as TDS, are inorganic compounds found in water such as salts, heavy metals and some trace organic compounds dissolved in water.

High concentrations of dissolved solids can change the taste of water, making it salty, bitter, or metallic. High TDS values ​​also indicate the presence of harmful toxic metals. A high TDS value can harden water, cause deposits in pipes, dry hair, stain dishes, and render kitchen utensils unusable. Checking the TDS level in your water can help you avoid these issues in advance.

The level of dissolved solids in water can be determined using a TDS meter. Results are reported in parts per million (ppm) - a reading of 1 ppm means that the water contains 1 mg of dissolved solids per kilogram of water. According to the Environmental Protection Agency, the maximum concentration of TDS in drinking water is 500 parts per million.
