VSL National Metrology Institute

VSL manages and develops primary measurement standards and primary reference materials on behalf of the Dutch government. These measurement standards form the foundation for reliable measurements in science, industry, fair trade, and other fields. VSL also participates in research projects to develop newer and better measurement methods.

We ensure that measurement results from companies, laboratories, and institutes are directly traceable to national and international standards. We also calibrate measuring instruments on behalf of customers, produce reference materials, organize interlaboratory comparisons, and share our metrology expertise through training and consulting services.
