TDS Meter

If you're buying your own minerals it might help to have your own TDS meter! TDS stands for Total Dissolvable Solids, the amount of minerals or aggregates found in the water chemistry. Some uses include:

  • Verify the water you are adding Third Wave Water to is truly 'empty' as recommended (distilled water, reverse osmosis, etc).
  • Test your current water to see how many minerals are present.
  • NOTE: this will not define which minerals are present in your water, only that something is there.

*All orders placed before 2pm EST will ship the same day!*

If you are not satisfied with your product, we will make it right!

    Feeling Nerdy & It Feels Good

    Really love getting into more of the science of water and coffee. This TDS meter is teaching me more and more about the water I'm using for my coffee. Really love how simple it is to use and read. Love the design and that I can take it anywhere.
