Metrology of electric quantities

Electrical quantities – DC and low-frequency electricity /DC and low-frequency /DC and AC

We carry out COFRAC Accredited Verification Certificates and Calibration Certificates according to the ISO 17025 standard in DC and DC current, direct current and alternating current and in time and frequency, which may include calibration in:

  • Generator, dc potential difference
  • Voltmeter, potential difference in direct current
  • Generator, potential difference on sinusoidal signals
  • Voltmeter, potential difference on sinusoidal signals
  • Generator, DC electric current intensity
  • Ammeter, DC electric current intensity
  • Generator, current intensity on sinusoidal signals
  • Ammeter, current intensity on sinusoidal signals
  • Generator, electrical resistance
  • Ohmmeter
  • Frequency generator
  • Frequency Meter


These benefits include:

  • Functional test
  • Comparative measurements against our reference measurement chains, connected to the National Metrology and Testing Laboratory (LNE)
  • Editing a report


Our services are complete and standard. They are also made specifically on demand.

Compliance is established on demand, based on the characteristics of the verified instrumentation manufacturer, if no specific request is specified. The measurement uncertainty could be taken into account in the declaration of conformity at the request of the customer.
