AC6 Metrología, Calibración, S.L. joined the Applus+ Group in July 2017.


Applus+ Laboratories is a leading company in calibration and legal metrology services in Spain. Since July 2017, Applus+ has been operating a calibration laboratory in Orkoein (Navarra), which serves as an operational base for the region of Navarra and the Basque Country.


Accredited Calibration. The Orkoein laboratory (Navarra) has the ENAC accreditation number 26/LC10.017 to calibrate measuring equipment and standards in the following technical areas (find out about the scope of our Navarra laboratory in the Accreditations and Recognition section): 

Our technical calibration team in Navarra can calibrate other measuring instruments and issue a non-accredited Applus+ certificate for equipment such as:  Axle alignment equipment, Counter meters, Distance meters, ultrasonic thickness gauges, Ground resistance meters and Stiffness gauges. If you require an ENAC accredited calibration certificate for these or other instruments, Applus+ can offer this service through another laboratory in our network. Contact us.


Our network of laboratories and mobile units allows us to offer a local service throughout the whole of Spain. Our technicians can also travel to facilities if measuring equipment needs to be calibrated or checked on site.
