Electricity: DC and Low Frequency

Portrait

dclf_P

The accurate measurement of electrical quantities is essential in most industrial, economic and scientific fields. Be it temperature, acceleration, strain, displacement or proximity, the final step of a physical measurement will almost invariably take the form of the measurement of an electrical quantity (current, voltage, resistance…).

The laboratory DC and Low Frequency ensures the traceability of all measurements of electrical quantities to the SI units. The physical realizations of the volt and the ohm, via the Josephson and Quantum Hall effects respectively, are available in the laboratory. These fundamentally accurate primary standards are then transferred to the working standards through high quality instrumentation, often developed in-house. This allows us to offer a wide range of calibration services and has established the reputation of the laboratory as a top service provider, for instance, in the measurement of resistance or current over many orders of magnitude.

The laboratory is actively involved in new developments, both in industrial and more academic settings. We strive to be a reliable and effective partner, with evolving measurements capabilities, in step with the needs of our customers. 

Services

dclf_DL

We offer electrical calibration services of the highest accuracy but also consulting in measurement techniques for the industry as well as metrology courses.

Calibrations

With their considerable scope, our calibration services ensure that your electrical measurement equipment is traceable to the national realizations of the electrical SI units.
Our calibration certificates are recognized internationally. For this purpose, we operate a quality assurance system in accordance with ISO/IEC 17025-2005.

Consulting

If you have any questions concerning our services or need advice, we will be pleased to help. Contact us without obligation.
