Hey All, selling my Hanna ULR (HI781) Nitrate checker for $45 shipped to the lower 48. I have used it a few times but am no longer chasing low nitrates. It comes with about 20 of each solid reagent and half of the liquid reagent with a handful of filters which should be good for around the same number of tests. All expiring 07/25 so plenty of time to use. Works great and have not had any issues with the unit. Please PM for more details or questions.
