I have started work on a similar task a few weeks ago. I hope you are more
pleased with the Lamotte kit than I am. It is far more subjective than any
of the other tests I have gotten from them, especially at low levels. It is
a turbidity test that requires you to decide when the black dot is obscured
by the solution.
I started keeping all test results in Excel and monitoring the graphs for
trends about 6 months ago. I'm not sure why I hadn't thought of it years
