Resumen:
We describe the set-up of a new two-terminal cryogenic current comparator at the Instituto Nacional de Tecnología Industrial, Argentina. This new bridge improves our uncertainties in high value resistor measurements up to four hundred times in the best situation. Expanded uncertainties of 0.01 μΩ/Ω can be obtained to 1 MΩ or 10 MΩ resistors and 1 μΩ/Ω to 1 GΩ resistors.
