So my problem is backwards - I have the K-2006 kit which uses R-0004 and I bought the R-0014 by mistake. Can I just use a smaller sample size, like 20 mL, compared to the 44mL sample that I would use with R-0004? Would the shade of red give me an indication of what the pH is?
By the way, does anyone else equate the color to red wines? A high pH is like an immature fruity wine with lots of purple and pink whereas a low pH is like a well aged Barolo, more of a brick red towards an orangey-red.
