Review on ⚖️ Accurate TDS Meter Digital Water Tester: Third Wave Water 0-9999ppm for Optimal Coffee Brewing Water Composition by Rene Putman

I suppose that's pretty accurate. I have very hard water, but I also have a water conditioner. So my guess is that the value of 25.9 as shown in the attached photo is (fairly) accurate. Unfortunately I don't have any other quality control tool. However, in the second photo, Arrowhead is testing bottled water at 9:8pm. Based on the comparison and in my opinion, Arrowhead's bottled water tastes better than my tap water. I think the next two metrics I want to find out are whether my Brita carbon filter/water jug is working (or how well it's working) and what my relatives are getting from their reverse osmosis system. , I'm terrible at photography) and shows my relatives' reverse osmosis water parameters of 2.7! I think this year I will consider buying a reverse osmosis system.
