Accredited calibration primarily fulfils requirements for legal purposes.HBK can provide the following accreditation for our sound level meters：
- English certificate
- A2LA（English certificate）
- ENAC（Spanish certificate）
- NATA（English certificate）
- Portuguese certificate
初始计算
We recommend you order accredited calibration together with your new sound level meter，to start your calibration history from the very first day。
重新计算和度量
HBK recommends annual re-calibration to provide data for an unbroken calibration history.This can then be used asa reference for internal requirements，for auditing required by authorities，or at the request of your customers。
Measurements of sound level meters are according to standards IEC61672，IEC60651/60804，BS7580，ANSI S14，and ANSI S1.43.Initial calibrations on new sound level meters Types2250,2250Light and 2270will be performed according to IEC61672.This applies for calibration to according to accredbodies and NAK。
Re-calibration of Types22502250Light and 2270for DANAK and ENAC will be performed to the latest standard，IEC61672，unless you specify another standard on the order。
Measurements are traceable to institutions such as DPLA，NIST，NPL and PTB。
