    National Metrology Institute of Malaysia (NMIM) is established to support the industries and nation’s needs on the reliability of measurement unit in Malaysia. Its existence has evolved from a local calibration organization to positioning itself as standard laboratory which is recognized internationally.

  • calibration services
    Calibration plays an important role to ensure the accuracy of a measurement and quality control. It is essential to guarantee quality of products is at best due to competitiveness of various sectors arises nowadays. In addition to that, the science of measurement is crucial in economic development, social well- being, safety and health as well as public welfare. 
    NMIM functions as reference standard laboratory that provides traceability to the SI unit for mass (weight), length, time, resistance, voltage and density.

    The Mutual Recognition Arrangement of International Committee for Weights and Measures (CIPM MRA) is the supporting structure through the National Metrology Institutes (NMIs) in corroborate the international equivalence of their measurement standards and the calibration and measurement certificates issued by them. The technical basis of CIPM MRA is the set of results obtained for certain range of time through scientific key comparison carried out by the Consultative Committees (CCs) of the CIPM, the International Bureau of Weights and Measures (BIPM) and the Regional Metrology Organizations (RMOs).

RESISTANCE

Resistance laboratories provide the measurement traceability for resistance as well as development and maintenance of national physical standards for resistance. The laboratories provides calibration measurements with capability  from 1 m to 1 T. The National Standard of Resistance is a 1  and 10 k resistors kept in an oil bath at temperature of 23°C ± 0.001°C. The reference standard resistor is calibrated at BIPM on a regular schedule and disseminate to other resistors by using the automated DCC bridge at range of 1 m to 10 M. Resistance values below 1 achieved by using Direct Current Comparator Bridge with a Range Extender. The system has ratios up to 1000:1 with the relative uncertainty of 10-6. The resistance values from above 10 M are scaled up using a modified Wheatstone bridge by replacing Resistive arms with 2 DC Voltage. The resistance laboratories dissemination, capability and uncertainty are shown in following table and diagram respectively.
