PTB is among the top names in metrology worldwide. As the National Metrology Institute of Germany, PTB is Germany's highest authority when it comes to correct and reliable measurements. Research and development work amounts to about two thirds of all of PTB's activities.
Based on its research and development work, PTB provides a wide range of metrological services. The central task in this context – laid down by law – is to realize and to disseminate the units as accurately as possible. In this way, PTB ensures that uniform measures are used, not only in Germany, but throughout the world.
