Traceable references

For a better understanding of the climate: METAS has produced the first two traceable references for hydrofluorocarbons.

Measuring station under control

Extreme weather situations such as flooding or drought call for accurate monitoring of hydrological parameters. To ensure that this runs seamlessly from the technical perspective, METAS operates and renews the equipment in the 300 or so measurement stations belonging to the Federal Office for the Environment (FOEN).

The watt balance: an experiment to redefine the kilogram

In future, the kilogram is to be defined using natural constants instead of the international prototype kilogram in Paris. One of the experiments contributing to this goal is the watt balance.

Keeping a finger on the pulse of smart grids: PMUs

Monitoring of electricity grids is increasingly being carried out with so-called phasor measurement units (PMUs), tested and calibrated by METAS.

CTI research partner

Take advantage of METAS’s research and development expertise in the many different fields of metrology.


Certification Body METAS-Cert

The accredited conformity evaluation body METAS-Cert is a body notified by Switzerland and recognized by the EU for the conformity evaluation of measuring instruments. The conformity evaluation body METAS-Cert provides manufacturers of measuring instruments with the required conformity assessments for the placing of their products on the market.



METAS lays great importance on being an attractive training location. It offers six different apprenticeships in the fields laboratory (chemistry and physics), electronics, engineering and in the commercial sector and university internships.



METAS is where Switzerland is at its most accurate. It is so to speak the guardian of measurement units in Switzerland. Through its activities and its services, it ensures the capability to perform tests and measurements in Switzerland at the level of accuracy required to meet the needs of business, research and society.
