I have a Hanna low range nitrate checker available. It‘s in excellent shape and has 8 tests remaining from when it was originally purchased. I’m also including an unopened refill with another 25 tests, for a total of 33 tests. The only thing that’s missing is one of the small cuvettes. I accidentally dropped and broke it literally hours after I got the kit, during the first test I ran. You only use one small cuvette for the tests, though, so the second is just a backup.
I‘m asking $45 shipped for the checker and refill.
