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!

Keeps the reading active!!

This meter supplements water test strips. Tested against another, it is 100% accurate. I like that..unlike my old one, it retains the TDS reading till you turn it off. (BTW, I also love my Third Wave Espresso formula!

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.

I really like it!

I have really enjoyed having the TDS meter so that I know the exact number going in my espresso machine however it would be nice to know exact particles and stuff like that but since I'm using third wave water every time, I really don't need to worry about that however that would be good if at some point I want to use some other kind of water to tell me what exactly is in it which would probably be something much larger than just a small device like this. Otherwise I have really enjoyed using it and really like this device and love Third Wave Water!!!!
