Nano and Mechanical Measurement Laboratory

*

:::

The Nano and Mechanical Measurement Laboratory (NMML) has established the standards in the fields of mass, force, pressure,vacuum and nano. For the mass standards, a primary mass standard, Pt-Ir kilogram prototype, has been set up to provide the weight traceability. In the region of force, the calibration services are available for several types of force transducers. In the region of vacuum, the calibration services are developed for varieties of vacuum gages. In the region of pressure, a mercury manometer system has been established for different types of pressure calibration. In the region of nano, measurement systems for nanoparticle sizes have been established for different types and sizes of nanoparticle size calibration. In the region of thin films, measurement systems for thin film thickness and mechanical properties have been established to calibrate different types and thickness of films.

Calibration and Measurement Capabilities, CMCs

Since 2003, the calibration and measurement capabilities (CMCs) in the area of mass (M) have been incorporated in BIPM’s key comparison database (KCDB.) It declares that NMML's CMCs have gained international recognition and its availability of offering measurement service worldwide.
