If money's no problem then check this out : Rethink what a pH meter should be
Wow sorry you had much trouble with hanna. Since I'm partially color blind I find it very difficult using the color titration kits - api, red sea etc..Hanna meters were the worst thing that happened to our hobby. I mean to do a test for PO4 I had to spend my life cleaning the vials? You kidding me?
They suck3d then they do now. What a scam.
