Laboratory for Dimensional Measurements

Subjects of research and tests carried out by the Laboratory

• standard instruments measuring external and internal thread parameters
• standard measurement instruments for transferring the size of the length unit to thread master, reference master gages; reference plain gages
• measuring devices for external and internal dimensions of reference rings
• measuring devices for geometrical parameters (1D, 2D, 3D)
• measuring devices for geometrical parameters used in non-destructive tests
• realization of tests of devices of the domestic and foreign manufacturers with the purpose of the sanction of their use in territory of Russia
• accreditation of calibration laboratories of a number of industrial enterprises in Russia

Lines of scientific activity of the Laboratory

• study of noncontact photoelectric methods of pointing internal dimension gages to the measuring surface
• laser interference measurements of object-micrometers and diameters of cylindrical gages
• study into the methods of high resolution optical microscopy for measuring dimensions of aerosol, hydrosol and powder particles. This work is carried out in collaboration with the Department of Measurement Standards in the Field of Physico-Chemical Measurements
• experimental study and measurements in medicine and biology, in particular, in hematology
