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 Steven Pankey

Today I received the meter and immediately started playing with it. First my filtered water from the fridge. 35 ppm. Hm. My next tap water has 38.39 ppm. Maybe the water filter in my fridge really needs to be replaced. Next came purified water from a store-bought bottle. 3 parts per million. son of a gun. I said I started playing with him right? I'm sure I'll get serious later, but right now I think I need to think about replacing the water filter on my fridge.
