This triple scale gauge is the ideal range to read pressures for pressurised fermentation.
The triple scale gauge gives readings in Bar, PSI and kPA so irrespective of what units you prefer this gauge will display what you need.
The barb on this gauge will enable you to put this directly onto hosing or alternatively you can connect it to any of the push in fittings such as the Duotight push in fittings in the 8mm (5/16") Size.
