On 20 June 2025, the delegates from NIMT, led by Pol.Lt.Gen. Pornchai Suteerakune, Director of NIMT, took part in the Technical Tour organized as part of the APMP Mid-Year Meetings 2025. The tour offered an exclusive opportunity to explore the state-of-the-art laboratories at CMS\/ITRI and to engage in technical discussions on emerging fields of metrology.<\/p>\n
The morning session featured visits to four key laboratory facilities that demonstrated cutting-edge national measurement standards:
\n– Silicon-Sphere Kilogram Standard \u2013 showcasing the redefined realization of mass based on fundamental constants.
\n– Calibration System for Coordinate Measuring Machines (CMMs) \u2013 highlighting high-precision dimensional metrology techniques.
\n– Quantized Hall Resistance Standard \u2013 representing electrical resistance based on quantum phenomena.
\n– Acoustic Gas Thermometry \u2013 a primary method for high-accuracy temperature measurement using acoustic principles.<\/p>\n
In the afternoon, the NIMT delegation visited the Nanometrology and Automated Optical Inspection laboratories, which presented the latest developments in nanoscale measurements and automated quality control systems.<\/p>\n
The tour concluded with a focused technical meeting on medical metrology, where experts from CMS introduced ongoing developments in:
\n– Medical device evaluation,
\n– Molecular-level biosensor technologies, and
\n– A roundtable discussion<\/p>\n\n\t\t
