Technical Details

Sound level and vibration meters should be calibrated regularly. The Castle range of calibrators are designed for everyday site work. For annual authentication of calibration we offer a comprehensive calibration service traceable to National Standards, at our well-equipped laboratory in Scarborough. Many of our authorised overseas agents are also able to offer the service.

All instruments are tested to check compliance with particular specifications. These specifications may be appropriate British Standards, or if the instrument was not originally designed to meet any British Standard, or when the instrument was originally manufactured a relevant British Standard did not exist, the instrument will be tested to the manufacturer's original specification.

Absolute acoustic calibration of acoustic calibrators and sound level meters is checked at one or more standard frequencies against an independent sound source with calibration directly traceable to the National Physical Laboratory (NPL) in the United Kingdom.
