I have the Hanna Checker 1 pH meter. I didn't have any storage solution to drop into the cap of the probe so I stored it 4.01 solution. I turned it on after not using it for a week and it was reading 4.78!
I have little experience with pH so what I'm wondering, is the prode already wrong? does the pH solution go bad quickly? is it bad to store the probe this way?
