Ch testing (difficult getting accuracy)

[Tom09]

I’ve tested CH several times and is one of the most difficult tests. I used the fading test where I added 5 drops r-0012 to begin. Here is some pictures, it’s hard to see, there was color particles floating around when stopped. After the test , it changed back to purple. Not sure if this is accurate.

The first one is the start of the test after the 5 drops of 0012 and the last picture is how it changed back to color. The prior picture where it’s blue is 13 drops at 10ml

I'm not sure if this helps, but you appear to be doing the test differently from the instructions that Taylor provided with my test kit.

Thank you for that clarification. I have never used that method, so hopefully one of the experts will be able to help you.
