Calibration of sound and vibration measuremnt instruments to ensure measurement quality

Calibration and verification

Regular calibration ensures high data quality and documentation, minimizes the risk of errors, and reduces associated costs

By calibrating measurement products on a regular basis, you ensure high data quality and documentation, minimize the risk of errors, and reduce associated costs. Our comprehensive range of calibration services help you meet national and international requirements regarding:

Accredited calibration including measurement results (recommended):

  • Traceable to national institutes (DPLA, NIST, NPL, PTB)
  • Proof that calibration is in accordance with ISO quality standard
  • The certificate 
    • can be used as legally accepted documentation
    • is internationally recognized (based on mutual recognition agreements)
    • includes measurement results and associated uncertainties

Traceable calibration including measurement results:

  • Traceable to national institutes (DPLA, NIST, NPL, PTB)

Verification (no measurement results):

  • Country-specific requirements (legal verification)
  • Instrument specifications (conformance testing)

Hardware maintenance:

  • Repair by highly skilled technicians
  • Extension of manufacturer’s warranty

Our calibration laboratories are accredited in many regions and fulfil the requirements of ISO A2LA and other standards. Brüel & Kjær also offers primary calibration for transducers through the Danish Primary Laboratory of Acoustics (DPLA), and field calibration for LDS shakers. All work is governed by ISO 9001 procedures, and customers are issued with a calibration certificate.

Accreditation equivalence

Brüel & Kjær operates its own calibration centre network within the European co-operation for Accreditation (EA) guidelines for accreditation. Accreditation bodies that are signatories to the European Co-operation for Accreditation Multilateral Agreement (EA-MLA) have granted all our accreditation. This means we are able to provide our customers with the same high level of quality, competence and confidence and EA approval wherever the accredited calibration is performed. All EA-MLA signatories recognize that they operate in an equivalent way to the others.

To ensure maximum uptime and minimize costs, we recommended that you combine calibration with a Hardware Maintenance Agreement, where Brüel & Kjær ensures that your hardware operates to specifications in normal use.
