To answer CarlD, I googled Taylor K-2006, and the one I looked at had this summary: "A complete DPD test kit designed for service people, commercial pool operators and health dept officials interested in economy & portability. Tests for Free & Total Chlorine (.5 - 5.0 ppm) Bromine (1.0 - 10 ppm), pH (6.8-8.2), Acid Demand, Base Demand, Calcium Hardness, Total Alkalinity and Cyanuric Acid. Uses 3/4 oz reagents.Plus Titrants to improve accuracy."

I do not want to break any rules about advertising, especially since I don't even know this company, so I will not say which google result I got this information from.

This is all like a foreign language to me, so thanks for your patience and help!
