Review on 🔬 Accurate and Reliable TDS Water Quality Test Meter with Large Backlit LCD Screen, Professional TDS and Temperature Measurement at an Affordable Price. by Jason Ortiz

So far I've tested everything I can get my hands on. My tap water (156 ppm) Yes, I have hard water! Golden Top Tea (52 ppm). Water where I work (77 ppm). All agreed and tested more than once at each location. I have experienced hot and cold. Same results. Will update when I have a chance to test more. Let it be known that I am not a professional water tester! I did some research and looked at the EPA guidelines.
