Customer Reviews:
A very nice tool to check the purified water vending machines located throughout the area. I buy water at water vending machines and I have always wondered if the owners maintain, and service the filters and purification machines. With this tester, I am able to quickly test the water and decide if I want to buy more water from a particular water vending machine. I have found most of the water vending machines to be in the TDS range of 9.3 ppm to 23 ppm range, but I have found some of the vending machines to be extremely high in the 100 ppm to 220 ppm. My home water is in the 100 ppm range. This tool is cool. I do wish that the test selection button was located near the top because it presentlhy is located down low, and I have trouble reaching it while testing water in a glass. I also wish the probe sensors would reach 1 inch lower. But it is still an effective water testing tool.
