Electrical/Electromagnetic Measurement Laboratory



The research scope of the Electrical/Electromagnetic Measurement Laboratory (EEML) covers electricity, magnetism, and microwave. It has established standards in the three fields to provide traceability for domestic industry.  

In the area of electricity, the established systems in voltage and current provide complete calibration services to the local industry, including a variety of range from electrical power, electrical energy, phase angle, resistance to inductance, and capacitance. To meet the requirements from the semiconductor industry, the EML has established Sheet Resistance Measuring System in order to provide the calibration for semiconductor reference materials.

For magnetic standards, the laboratory has established magnetic flux, nuclear magnetic resonance (NMR) flux density, and low magnetic field measurement systems to provide calibration services.

In the RF / microwave area, the laboratory provides microwave power, impedance, attenuation, thermal noise, electromagnetic field, and microwave material characteristics measurement services.

Calibration and Measurement Capabilities, CMCs

Since 2003, the calibration and measurement capabilities (CMCs) in the areas of electricity and magnetism (EM) have been incorporated in BIPM’s key comparison database (KCDB.) It declares the best measurement capabilities for calibration services.
