VSL has expanded its K999 scope with a new accreditation for vacuum calibrations.<\/h2>\n

 <\/p>\n

With this addition, VSL aims to meet the growing demand for reliable and traceable vacuum measurements within the Netherlands and abroad.<\/p>\n

 <\/p>\n

The new accreditation enables companies and research organizations to obtain vacuum calibrations with short turnaround times, ensuring accurate and traceable results. With this expansion, VSL further strengthens its position as a leading national metrology institute and supports organizations in improving the accuracy and reliability of their vacuum measurements.[\/vc_column_text][vc_column_text css=””]<\/p>\n
