Pressure gauge for E61 brewing group

The pressure gauge shows the current pressure at the brewing head during the brewing process. It is therefore more accurate than the brewing pressure between the pump and the expansion valve shown on the machine. Pre-infusion, pressure build-up and extraction can be precisely monitored.

To install, simply remove the small Allen screw at the front of the brewing head and screw in the pressure gauge with the copper washer by hand.

Not suitable for E61 brewing groups from Vibiemme.
