I called Taylor and they said the factor is to divide my readings by 2.25. Surprising me is that comes out to .6ppm (3 drops x .5ppm) / 2.25 when I thought I had 5ppm or so based on the other kit I have. It's showing 0 CC so that's good I guess. I have the other kit on the way and will still do a direct comparison and report back.
