National Metrology

Measurement at NSAI is split across two divisions within NSAI; Legal Metrology and National Metrology Laboratory (NML). 

NSAI National Metrology Laboratory maintains national measurement standards for a range of physical quantities. These standards represent the best available representations, in Ireland, of the internationally agreed units of measurement.NML offers a range of calibration services including, acoustics, electricity, force, humidity, length, mass, pressure, temperature, time and frequency, and torque.


National Metrology Laboratory (NML) offer calibration services for the following areas, please contact us for a quotation

Approval Status

The National Metrology Laboratory (NML) has responsibility for the realisation and maintenance of the national measurement standards for Ireland and the provision of traceability to users.

The National Standards maintained by NML and the calibration certificates issued are approved under the CIPM MRA. NSAI NML are also certified to ISO9001.
