In the 80’s Marcellino Zanesi, CEO of Nuova Ricambi, designed the tool that 30 years later continues to be used by the professionals repair technicians around the world for the perfect setting of the espresso machine: the filter holder with manometer to measure the pressure of the incoming water.
In 2006 the filter holder has been implemented with a hole that allows the entry of the digital thermometer sensor directly into the filter holder body it is possible to make a check on the water temperature in dispensing with the reliability of an instrument able to detect temperatures, with a range of -50°C+300°C(-58°F+572°F).
A tool as simple as it is ingenious: simulating the effect of water in the dispensing of the coffee tablet, the pressure gauge connected to the filter holder allows to accurately measure the pressure exerted on the group, in order to check if there are losses in the circuit. The data is displayed in real time and thus make it possible to adjust the dosage without using the coffee.
Avere dei parametri di controllo coretti permette ai tecnici-riparatori professionisti di regolare il settaggio della pompa e della valvola di espansione. Grazie alla facilità di utilizzo permette anche ai baristi più esperti di poter verificare il settaggio della macchina in autonomia.
