***Brand new dial: Black and white, wider measuring range 0 - 18 bar***

E61 group pressure gauge M6 thread fits most E61 coffee machines on the market such as Rocket, ECM and profitec.

You may monitor the extraction of the coffee acurately as the gauge is installed close to the water dispensed from the shower screen. The reading generally is much more precise and close to the real brewing pressure.

The ideal extraction is 9/10 bar and pre infusion 2.5 bar approx.

Please note:

This fits most E61 groups - but not all, as the angle on some groups will prevent fitting.
Works effectively, when coffee is in the portafilter or using blind filter to test pump pressure.

Will not fit:
