I read here on a posting someone suggested using 1 less drop of indicator to get a better color comparison.
I started doing that and I am finding using 1 less drop of R0004 indicator during the pH test, I get a much better idea of color match, seems that the color intensity is less and matches the comparator color.
Is this OK to test this way or not?...I just did another pH test used 4 drops, color matched at 7.4, added the 5th drop still 7.4 but color was more intense and harder to match (I am using the comparator that came with the K2006 kit filled to the 25mL mark)
