Just bought this last time it was on sale haven’t used or calibrated it yet because I have a questions on that calibration and instructions are not very clear. Doesn’t anyone know if you but the PH calibration packet powder in distilled, RO, or tap water when doing the calibration?
I did the same thing and used RO because I had it on hand for a brew coming up. I think distilled would be good too but I’d avoid tap.
