For all equipment suppliers, manufacturing industries and laboratories now implementing the means to measure electrical potential differences, resistances and impedances, LNE provides a wide range of services to characterize your instruments and/or facilities: Confirmation of your references, matching of your working standards with your equipment.
Traceability is guaranteed by correlating the unique standard resistance values of 1 W and 10 kW with the QHE (Quantum Hall Effect).
Traceability is guaranteed by correlating the unique standard capacitance values of 10 pF, 100 pF and 1000 pF with the Lampard-Thompson capacitance meter at a frequency of 796 Hz.
Traceability is guaranteed by means of correlation with the direct current resistance and capacitance standards.
Traceability is guaranteed by correlating the unique standard voltage reference values 1.018 V and 10 V with the Josephson Effect.
Uncertainty levels I and II, in accordance with your needs.
Uncertainties available either on the COFRAC website or upon request.
