I bought this to test my RO water to make sure most everything was taken out and also as a tool to estimate coffee extraction. Seems to be doing the trick with no problems!
Perfect combination to improve your coffee. Tds was an impulse purchase but it is an interesting metric if a bit of a novelty.
Works as described. Reads the TDS level instantaneously.
very simple foolproof meter that guarantees accuracy in my coffee making.
Very illuminating to use this meter. I got 102 from my RO system, 387 from tap water, and 277 from the RO water with Classic Profile added. It's put my mind at rest.
