Review on Extenuating Threads Digital PH Meter: High Precision Water Tester Pen for Household Drinking Water, Pool, and Aquarium PH Measurement (White) by Neil Bodell

Very easy to use. I was able to monitor the pH of my baby's water because her skin is sensitive. There are a few important points to bear in mind. Make sure to use distilled water for cleaning before and after use. Don't skip this step. Calibrating was fun, I felt like a scientist. I used small disposable cups which I rinsed with some distilled water before testing. Do not hit the sides of the bowl while stirring. Stay in the middle. I think of it more as twisting than mixing. I chose this article because I want to be aware of the quality of the water around me. It fits in my purse so I can easily use it on the go. LED reading is also easy to read. Only two buttons to control the device. I recommend families to order one.
