Sending a notification regarding the marketing of measuring instruments in Portugal (mutual recognition)

In order to market measuring instruments in Portugal that are not yet on the Portuguese market and are already lawfully marketed in at least one European Union (EU) Member State (MS), the economic operator must send a notification of compliance with the requirements for mutual recognition.

There are various measuring instruments, such as manometers, time counters, radar cinemometers, tanks, to name a few.
