Thanx Adam! However they only supply the low range test kits...which are
great once you have your nitrate levels within normal bounds. I would also
need medium to high-range kits as well. I know LaMotte sells #5891 which
does 0, 5, 20, 40 ppm and #3519/NCR-2 which does 0.25 - 10.0 ppm. Does the
second tester only show 4 values 0,5,20, 40? Or will it show some in
between.Would it be a good idea to have both testers?

Thanx!

Dave.
