When testing for TA using my K-2005 kit, I'll reach a point where the sample will turn a faint reddish color, and hold that color (it won't flash back to green); the next subsequent drop of acid will cause the sample to turn a deep red color. Should I go with the reading (drop) that caused the initial color change, even though it's faint, or with the next drop which produces a deep, distinct red coloring? Or just go in between, as it's 10ppm per drop? Or should I quit being so anal about it, and just figure "what's 10ppm between friends?" :lol:
TIA,
Mike
