Which Hanna PH Checker Is The Best ?

[427HISS]

They seem to have several type's and prices, so which model is the best and most accurate ?

Any. None. Sorry to be flippant, but they all need regular calibration or they are not worth much. Any of them are good if you keep them calibrated.

Why not just get a good cheap Ph tester?

And unless your running something that can greatly alter Ph you really don't need to worry about it anyway.

If a lower cost meter is accurate, I'd but it. I'm just getting tired of the test strips. I'm one that keeps and eye out on everything. Not just my aquariums either,
like with my cars and women.
