Calibration of Noise Dose Meters

For Noise Dose Meters Brüel & Kjær can provide Accredited Calibration, Traceable Calibration and Instrument Verification.

Accredited Calibration

Accredited calibration fulfils requirements for legal purposes and is recommended for other purposes.

When a Noise Dose Meter is used to measure results for public purposes, or possible trials, calibration must be accredited. Country requirements state how often calibration must be performed.

Brüel & Kjær can provide these types of accreditations for Brüel & Kjær Noise Dose Meters:

• DANAK (English certificate)
• A2LA (English certificate)
• RvA (Dutch certificate)
• ENAC (Spanish certificate)
• Inmetro, Brazil (Portugese certificate)

Initial Calibration

To start the calibration history from day one, we recommend you order accredited calibration together with your new Noise Dose Meter.

Regular Re-Calibration

For Noise Dose Meters we recommend regular calibration to provide you with unbroken calibration history to use as reference, either for internal requirements, or at the request of your customers.
