Hanna checker question.

[Kristin1234]

I am upgrading my test kits and looking to buy a Hanna chexker for my phosphates.

I see 2 of them, one that checks for high range and one that checks for low range.

Which one do I want? Lol

I would prefer not to buy both.

I'm thinking the one that checks the high range?

Low range. You can always dilute your sample if it is too high
