I have some too. The .2 is good for checking the pH of spit and urine, I did that for awhile, and I tested my water too while I was fooling around :-)

I was using the pH testing tape because my son thought perhaps acidity of the CS was what caused it to make his tongue and throat tingle.  I have 15 feet of tape in a roll, .2 increments, for $10.80 which I found at a small health food store, after finding only the .5 increment tape at a couple larger stores.  It says "for use with bodily fluids only"on the box, so I don't even know how accurate it is for water testing, but should be ok, huh?                                                                                                       Pat
