Review on 📏 Improved Measurement Resolution of HM Digital ZT 2 by Steve Cooper

When I bought a Zero Water filter and jug last year, I bought a tester that only flashed red when the water wasn't clear. But I needed an accurate reader and couldn't be happier with this one that has a digital readout - both Zero Water Testers. Using a digital meter before I filtered tap water through a Zero Water Filter, the reading showed 207 ppm dissolved solids. When I tested it on my new meter after filtering, it read ZERO. I'm sure I'll save a lot of money if I don't buy bottled water!
