    CH Test with TF-100

    TF-100 came today so of course I've been getting familiar with it and doing my testing. I have a question about the CH test though.

    Do I mix/swirl the solution in between drops of R-0012 or just add the drops steadily until the color completely changes?

    Swirl between each drop of R-0012. Give it a chance to react.

    All that swirling for the Ch test is the main reason I love my magnetic stirrer!
