METROFOOD-RI is a Research Infrastructure (RI) for Promoting Metrology in Food and Nutrition composed by a Physical (P-RI) and an electronic (e-RI) infrastructure which are strictly interconnected. PRO-METROFOOD Project (H2020 INFRADEV-02-2016, GA n.739568) represents the “Early Phase” of the RI and has among its objectives the definition of the operational capacities of the P-RI, with the design of its scientific services. The facilities have been inventoried and classified in a database, which provides an organized overview of the capacities of the distributed P-RI.
