NT-MDT calibration grating with calibration certificate of international standard
NT-MDT calibration gratings have been included in Russian state register as measurement instrumentations of nanometer diapason relief measures.
Below you can find their numbers in the State register:
Inspection and calibration of the gratings were made by Russian research Institute for Metrological Service (VNIIMS). Thus the NT-MDT calibration gratings can be supplied with international calibration certificate.
VNIIMS’s calibration abilities in the field of geometric measurements are acknowledged by Bureau International des Poids et Mesures (BIMP), Paris; Coomet, PTB (Germany) etc.
Thus possessing NT-MDT calibration gratings with VNIIMS certificate you get international recognition of your work results.
