Calibration and Verification Services

Regular calibration ensures high-quality data and provides measurement documentation. Calibration and verification greatly minimize the risk of error, and costs in securing product quality, and consequently, customer satisfaction. With our extensive services, we ensure you meet national and international regulations and legal requirements. 


Accredited Calibration

With 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

With measurement results

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


Without measurement results

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

Hardware Maintenance:

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

To ensure maximum uptime and reduce costs, we recommended that you combine calibration with a Hardware Maintenance Agreement to ensure your hardware operates as expected.

Service Center accreditations

HBK has 9 regional service centers for Sound & Vibration products. They are in Denmark, France, Germany, Spain, Austria, USA, Brazil, China, Japan, and Australia. Most of the centers are accredited by local accreditation bodies. Below are certificates for some of the accreditations:

A2LA HBK Certificate of Accreditation Duluth 2021 to Sep-2023

Certificado de Acreditação n 0305 - Spectris do Brasil

CNAS Accreditation Certificate_English - July 2020 to Mar-2024

NATA Accreditation 2021-12-20

Accreditation Equivalence

Brüel & Kjær operates its own network of calibration centers within the European co-operation, upholding to the Accreditation (EA) guidelines for accreditation. The accreditation bodies that are signatories to the European Co-operation for Accreditation Multilateral Agreement (EA-MLA) have granted all our accreditation. 

The equivalence means you are provided with the same high level of quality, competence, confidence, and EA approval wherever the accredited calibration is performed.
