We demonstrate quantum Hall resistance measurements with metrological accuracy in a
small cryogen-free system operating at a temperature of around 3.8 K and magneticfields
below 5 T. Operating this system requires little experimental knowledge or laboratory
infrastructure, thereby greatly advancing the proliferation of primary quantum standards for
precision electrical metrology. This significant advance in technology has come about as a
result of the unique properties of epitaxial graphene on SiC.
