Legal Metrology 
Radar cameraLegal metrology comprises all measurements carried out for any legal purpose and includes measurements that are subject to regulation by law or government decree. It has its historical origins in the need to ensure fair trade, but also includes measurements in areas such as health and safety (e.g. sound level meters and radiation dosimeters) and traffic control (e.g. vehicle speed and breath analysers).

To support the needs of the national measurement system, NMI appoints three categories of legal metrology authorities: approving authorities, certifying authorities and verifying authorities. Click here for a list of appointed legal metrology authorities.
