Taylor Fas-DpD Test Kit K-2006

[hvactech2]

Let's do a chlorine demand test. You'll need a cheap OTO kit, as well as the K2006.

Ok I did just as you said and the color was kinda a reddish orange, not sure if I would say it was dark, I retested an hour later and there was no change in color.....maybe I should've snapped a photo.
