Why do you need a third-party calibration in an accredited lab

Be aware that each recognised acoustic instrument has been certified with a standard, shown at the back of the device. For specific projects such as government projects, it is mandatory by contract that the contractor provides acoustic measurement services with recognised acoustic measurement equipment. Ensuring the measurement accuracy, we, as an accredited acoustic calibration lab, are here to set up a professional calibration test for the user to verify the authentic functionality of the instrument.

Our Acoustic Calibration Centre has been accredited by Hong Kong Accreditation Service (HKAS) under the Hong Kong Laboratory Accreditation Scheme (HOKLAS) for calibration services as listed in the HOKLAS Directory of Accredited Laboratory available from its website (https://www.itc.gov.hk/en/quality/hkas/doc/scopes/302.pdf).

Our technology and knowledge enable us to calibrate both sound level meters and calibrators of Classes I and II variations. All calibrations are completed following a wide range of international standards, including:

Calibration services accredited by HOKLAS:

  • IEC 61672-3 Ed 2.0 (2013)
  • In-house test procedure ESG-Noise-001 against the IEC 61260:1995 requirements
  • In-house test procedure ESG-Noise-003

Please refer to Scope of Accreditation at https://www.itc.gov.hk/en/quality/hkas/doc/scopes/302.pdf for the specific tests or property measured.
