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 Darryl Blumenthal

I was a little skeptical when this arrived as my reverse osmosis water read 250! I figured something was wrong with the meter, so I went to my local water store that sells reverse osmosis water and asked if we could compare the readings. To my surprise, both mine and her counters showed just one dot apart. (9-10) I started working on my reverse osmosis system and found I had a faulty valve that needed to be replaced. Changed that and all filters and now I'm happy with my readings. 12. Beautiful Counter!
