metrologiinstitut

A metrologiinstitut, often referred to as a national metrology institute, is a public or publicly funded organization responsible for metrology within a country or economic region. Its core purpose is to ensure the reliability, traceability, and universality of measurements used in science, industry, commerce, and daily life by maintaining national standards and advancing measurement science.

Key functions include realizing and maintaining the national realization of the SI units, operating primary or national standards, and disseminating measurement capabilities to laboratories and industry through calibration services, reference materials, and quality systems. The institute also conducts research and development in measurement science, develops new measurement techniques, and provides technical expertise to address emerging metrological needs.

The institute coordinates with international bodies such as the BIPM and CIPM, participates in international comparisons, and helps translate global SI definitions into practical laboratory realizations. In many jurisdictions it also bears responsibilities in legal metrology, ensuring that instruments used for trade, health, safety, and environmental protection comply with regulatory requirements.

Typical activities include calibration laboratories, proficiency testing, certification of measurement procedures, and technical consulting. The institute often collaborates with universities, industry, and other national laboratories to promote measurement consensus, ensure traceability, and foster innovation and quality in the economy.

Ranging in name across countries, metrologiinstituts are usually publicly funded and linked to broader scientific or regulatory frameworks. They maintain measurement facilities in areas such as mass, length, time, temperature, electricity, and specialized domains like acoustics, radiometry, and chemical analysis.
