The Rocket Evoluzione Version One Boiler Pressure Gauge is still available from Rocket Espresso, though the wildly popular Version Two is the current model. This is a white dial. On the semi-automatic espresso machine with a rotary pump, one dedicated gauge is for the pump pressure and one for the boiler pressure control.
