Review on Highly Accurate and Reliable 3-in-1 Professional Water Test Meter: TDS, EC, and Temperature. Complete with Protective Leather Case. by Lance Story

We live in an area where you really can't drink water. After installing an entire home water filtration system, water softener, and UV system, I had to test the water regularly to make sure everything was working. I compare the readings of tap water with water from different bottles. This tester does an excellent job of determining TDS parts per million. I also brought samples into town to ensure my readings are reliable and worth the money as city tests have proven.
