TA test question

[jake556]

I am using the TF 100 TA test, And Im inbetween calling the results 120 or 130 TA based on color, 130 is a Dark Red pink while 120 is a definite change in color. Not sure it matters much but which would you go with?

Keep going until there is no color change. Don't count the drop that results in no change.
