Yea, it goes up in .2 increments. The one that I got from walmart about 12 years ago had a color chart to go by. I have a meter now. Actually, they still have the same one because I saw it the other day buying airstones. It may have gone to 7.6I got a pH test kit from an aquarium when I first started, it measures from 6.0 to 7.6 but not all of the points in between (6.0, 6.4, 6.6, 6.8, 7.0, 7.2, 7.6)
