Programmable graphene resistance standards

The project will develop and test programmable resistance standards of graphene.

Realization of electrical resistance in alternating current

The project has developed measurement systems and graphene samples for the realization of electrical resistance in alternating current and impedance using the Quantum Hall Effect. Using the new methods the calibration of standards…

Superconducting graphene arrays (SUGAR)

The project will develop next-generation electrical resistance standards and thereby improve the realizations of resistance, current and mass. The technology is based on so-called Quantum Hall Arrays built with the nanomaterial gr…

Calibration of inductance

The national Laboratory for electrical quantities offer calibration of inductance standards and various types of instruments, such as bridges, LCR-meters and inductive voltage dividers.

Calibration of capacitance

The national Laboratory for electrical quantities offer calibration of capacitance standards (capacitance and dissipation factor) and different kinds of instruments. For example, electrometers, calibrators, and LCR-meters.

Electric voltage

Electric dc voltage is an area of expertise at the National Measurement Laboratory for Electrical Quantities. We realise the unit related to electrical potential difference (voltage), volt, by utilizing the Josephson effect. …

The National Laboratory for Electrical Quantities

RISE is Sweden's NMI (National Metrology Institute) and is, according to the Swedish constitution, responsible for the central measurement quantities in the International System of Units, SI.

Electrical resistance

Electrical resistance is an area of expertise at the National Measurement Laboratory for Electrical Quantities. At our laboratory the resistance unit is realised  with the highest possible accuracy. In addition…
