In 1993, the institute received the status of the State Scientific Metrological Center.
In 2008, SNIIM creates the State primary standard for the unit of surface density of heat flux (GET 172–2008).
In 2013, the Institute develops the State primary standard for the unit of angle of phase shift between two electrical signals in the frequency range from 0.1 MHz to 65 GHz (GET 207–2013).
The institute creates, investigates and improves state primary standards, explores new physical effects.
SNIIM improves measuring methods, sets the values of fundamental physical constants, it is engaged in determining the parameters of the Earth's rotation etc.
