Test chlorin strength?

[Poconos]

Interesting question. If you have a way to measure small quantities accurately, like 0.1 ml or even a milliliter, then you can do repeated dilutions. Diabetic hypo needles are great for this. 10% chlorine would be 100,000 PPM, so if you take 1 liter of unchlorinated water and add 1 ml of 10% chlorine you get to 1000 PPM. Keep diluting until you get to something like 10 PPM or so, that you can measure. Sounds like a good experiment for this morning.

For what it's worth. Just did a check of some 6% Walmart Ultra that's been sitting around for a couple months. First diluted 2000:1, then 5:1 which is an overall of 10,000:1. Got 3.6% (3.6 PPM read with a Taylor K-2006) Hmmm ! Will continue to pursue this issue. Now I'm really curious.
