Results for Keyword standards of measurement

Impedance and Resistance Research

Research is underway to develop improved resistance standards based on the the quantum Hall effect at ac, to improve the calibration chain relating resistance to capacitance, and to provide 1 ohm standard resistors of exceptional electrical stability.


Mass and Related Quantities Research

Research supports the measurement of density, flow, force, hygrometry, mass, pressure, viscometry and volume.


Length and Related Quantities Research

Research activities are being undertaken to develop improved laser wavelength standards and to provide traceability for coordinate measuring machines.


Low Frequency Electrical and Magnetic Quantities Research

Research is being undertaken to develop improved standards for voltage, power and energy.


Photometry and Radiometry Research

Recent research has concentrated on establishing a cryogenic radiometer as the Australian standard for the candela.


Power Systems Research

Current research is focussed on high-voltage measurement systems, high-voltage insulation, impulse voltage measurement systems and applied dielectrics.


Temperature Research

Recent research has been directed towards improving the accuracy of the temperature scale, developing thermocouples with greater accuracy and investigating the use of thermoluminescence to measure high temperatures.


Time and Frequency Research

Our research is centred on dissemination of time and frequency signals and is focused on three key techniques: NTP, GPS time-transfer and optical fibre.


Time and Frequency Dissemination Service

NMI provides GPS time-transfer system, GPS integrity monitoring, NTP servers, telephone dialup service for synchronising computers and ABC TV-sync pulse monitoring in Sydney.


Physical Metrology Calibration and Testing

NMI's calibration and testing services are the highest accuracy measurements available in Australia and they provide traceability to SI units of measurement.
