Calibrations

Planning and implementation of mechanical and electrical calibrations.

Calibrations

The following mechanical and electrical calibrations are performed in our laboratories:

  • Dimensional
  • Mass
  • Torque and Hardness
  • Pressure
  • Electrical
  • Temperature and Humidity

Legal metrology

The Technological Institute of Aragon has been granted the status of Designated Body ODV-01 by the Government of Aragon, and the Legal Metrology Laboratory performs metrological testing on non-automatic weighing instruments (NAWI), vehicle tyre pressure gauges for public use, thermometers and temperature recorders; thereby determining if the measurements these instruments make are acceptable and are performed in accordance with the provisions of the regulations of the Ministry of Development and the relevant recommendations of the International Organisation of Legal Metrology.
