Coffee makers with pressure gauge

Pressure gauge

— an indicator that displays the pressure in the coffee maker tank. This function is found mainly in espresso makers (see “Type”): for efficient espresso preparation, increased steam pressure is required, while the pressure gauge allows you to control the status of the coffee maker and check whether it is ready for use. Also, such equipment will be useful from a safety point of view: you cannot open a pressure tank, you must first make sure that it has decreased to a safe level.
