I had a suspicion that my ph meter was going off frequently, so I bought another one. Im very particular and I like for things to work like people claim. So when my second one came in, I tested it against the 7.0 ph buffer solution and tap water. I did the same test with my older ph pen also .... The readings where different, so one of the 2 was wrong. So just out of curiosity, I decided to by an aquarium ph test kit and use it to test with the other 2. They all read different. Before you call me a dummy, I knew that ph in water changed with temperature changes. I just did not know how much and how fast. I had dropped from 6.8 to 6.0 in 5 minutes .... So when I used all the meters at the same time withe same water at the same temp.... I got the same reading on all ph meters. Lesson learned, and Im to damned obsessed lol. Here is some reading to back this up... http://www.chemguide.co.uk/physical/acidbaseeqia/kw.html ....
