Parameter testing question

[Fesso]

Hanna Checkers are the way to go. They are around $50-60. One you have the checker you only need to buy regent refills and so they aren't too expensive in the long run.

I love those Hanna checkers! Those look perfect - I'll grab a couple that I'll be using often and then just take my water in to the LFS for more specific testing. Thanks a lot!
