Flow control dimmer is NOT included.

Brew at the right pressure with a flutter-free gauge:

The dynamic pressure gauge gives you insight on what happens in the filter basket while brewing. Not only is it important to pull the shot at the right pressure, but the gauge supports your understanding of good preparation, and helps fast-track your learning curve.

The pressure gauge is essential if you decide to explore pre-infusion, pressure profiling and/or “lever like shots” with a flow control dimmer, for even better result in your cup.

This gauge is glycerine filled to eliminate needle flutter, has a sleek dial that sits in line with the front of the enclosure, and is made of durable stainless steel that perfectly matches the design of the Classic.

Unlike in other gauges on the market, the capillary tube can be unscrewed and replaced if ever needed, and it also has an in line 0.6mm orifice to ensure the needle is totally flutter-free.

A streamlined design with no compromises:

The gauge could either be mounted to the front panel of the Classic (this option requires a 41.3mm or 1 5/8″ hole to be cut) or wrapped in a streamlined enclosure that nicely fits the machine. The tilted design provides clear view angle of the instrument. Durability and heat resistance are guaranteed by the 3D printed ASA material. I have designed the enclosure so that it can be moved out of the way in no time, while the machine is serviced; routine maintenance and servicing can be easily performed without the need to disconnect any components!

CONS:

– The pressure gauge dial is only up to 11 bars, however it is happily whitstanding the maximum pressure of the machine

– Installation:

• seized bolts (3 way valve, OPV or water inlet) could be really stubborn during the installation

Panel mount option:

– Cutting a hole to the machine makes this an irreversible modification.

– On a Classic Pro or EVO the indicator light bracket has to be fabricated during the installation.

Top/Side/Rear mount option:

– The enclosure is 3D printed, so printing layers are visible.

– Increased height of the machine (top/rear mount options) (40-85mm or 1  9/16-3 1/3″)

– Exposed capillary tube (side/Rear mount options) could be annoying for some people.
