I have a Hanna alk , Hanna nitrate LR , both for 30 a piece do come with reagent and all parts. one of the cuvette in nitrate checker broke when I ordered it so there is only 1 but that’s all you need . Have only used these less than 5 times each they are just too much work for me I’d rather use the red sea titration for testing . Can ship if you pay the cost.
