This is the acquisition of a Cryogenic Current Comparator, mainly intended to be the comparison system that ensures the first step of traceability between the National Standard of Electrical Resistance based on the Quantum Hall Effect and other materialized patterns of this magnitude. Likewise, the equipment will allow the calibration of transformers and amplifiers of direct current and, combined with the national standards of electrical resistance and voltage, can constitute a quantum generator of current intensity directly traceable to the current definition of the ampere in the International System of Units (SI).
