I'm not sure, but I would suspect that a common probe reacts to the resistance change relative to ph in water. This would assume a constant voltage and the control circuit sensitive to changes in amperage. I'll buy the beer and supply the bench meter if you're willing to sacrifice a couple of probes.:D
