You can use it to easily retro fit your coffee machine with the best quality gauge, so you can monitor the pressure extraction from inside your GH.
Depending on the readings, you could find some possible errors on your coffee puck, like bad tamping, bad grind size setup and so on.
The ideal extraction is around 9 bar and pre infusion at max 2.5 bar.

And you’re done !
