Electrical Metrology

Measurements International's Quantum Hall Resistance (QHR) systems provide primary laboratories and National Metrology Institutes with a highly precise method for realizing and maintaining the ohm. Based on the quantum Hall effect, these systems provide a direct connection between resistance measurements and fundamental physical constants, supporting the highest levels of accuracy, stability, and traceability in electrical metrology.

MI's QHR technology combines precision measurement instrumentation with advanced cryogenic systems to provide practical, automated quantum-resistance measurements. Applications include primary resistance standards, quantum Hall effect research, resistance calibration, and the transfer of quantum resistance values to conventional resistance standards.
