hey jim,
i use a titration test and ph meter together.
using a ph meter to check for the end point takes all the guess work
out of the end point. many on the board have said that the endpoint is
when you measure a ph of 8.2, however, my bottle of blueing solution
says to measure to 7.0 so that's what i do.
good luck,
gus
