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!
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.
Easy to use and accurate! Highly recommend 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!!!!
