R-0004 and R-0014 are phenol red, an organic dye that changes color with pH.
We all wish for that!I usually do all my testing indoors usually in the evening or at night. I have always had a difficult time with the PH readings, no matter where I do it. Since I log my daily tests on my computer, I have found that opening a Blank Word processing screen and holding the test cells close to the screen at arms length gives me the best results. The other option is possibly hold it with the Speed Stir LED's on behind it. I would love a good, accurate, affordable, Ph test that didn't require me to have to compare colors.
