I just got an AC3 with temp/Lab pH probe. I calibrated it but I am not sure if it is reading correctly. When I test aerated DI water I get ~ 7.0, but when I test a saltwater mix (reefcrystals at 1.026 using calibrated hydrometer @ 78F) I get ~ 8.2.
I have another handheld probe (calibrated, etc.) that Ive been using and when I test the same batch of saltwater I get a pH of 8.4 (which is about what I would expect).
Anyone else with these ever have a bad one right out of the package?
thanks
