Can someone recommend a decent, but cheap PH gauge? (under $50 would be nice)
I have a rapitest analog style ph meter, but I do not trust it.
I read that digital ph meters need calibration, special treatment with chemicals for storage, cleaning, etc. is that true?
I am hoping for something simple and easy, just stick it in and get a reading.
Ideally that will work with soil??
