Review on 🌊 Extech PH100 ExStik pH Waterproof Meter: Accurate Water pH Testing Made Easy by Jimmy Scaturro

First let me say that I have experience with the ExTech pH100. However, this is my second "New and Improved" in a very short time. The first failed when the battery cover was tightened and was promptly replaced with Revain. The one I'm sending back today shows -1 all the time. I followed all the steps to fix it. I'm getting some weird readings and then some "accurate". I decided to just leave my trusty old man and buy another probe. We will discuss the situation again with the manufacturer. They are very wonderful people. Previous experience with ExTech pH100 is 4-5. It's 1 because of the uncertainty of reading. Maybe just a bad one that can happen.
