Acoustic Calibrators

Acoustic Calibrators to perform Field Calibrations on Sound Meters

When you're ready to take noise measurements, it's strongly recommended that you perform a field calibration using an Acoustic Calibrator. You should calibrate your sound meter before you start to measure, and then once you've finished you should perform a reference check against the calibrator and make note of any drift that has occured. You can find out more about performing Field Calibrators by reading this post and watching a short video.

Annual Calibration by a Traceable Laboratory

LAB23, the latest guidances from the United Kingdom Accrediation Service (UKAS), states the recommended calibration intervals for different types of measuring equipment, including:

  • Personal Dosemeters - 1 Year
  • Microphones (Reference and Workng) - 2 Years
  • Sound Meters (tested to BS7580, where applicable) 2 Years
  • Sound Meters build to IEC 61672 - 2 Years
  • All other Sound Meters - 1 Year
  • Acoustic Calibrators - 1 Year

For a professional calibration and repair service with a fast turnaround, contact Castle Calibration or visit www.castlecalibration.com and search for your equipment.

  1. Class 1 Acoustic Calibrator

    Casella Class 1 Acoustic Calibrator

    £566.50

    This is the Class 1 Acoustic Calibrator, which is very small and housed in a rugged case which makes it easy to transport and keeps damage to a minimum. It is important that the kits are re-calibrated before and after the results are taken because the results may be distorted if the meters are not reading correctly and therefore you may not comply to the work regulation standards. The class two has a lower accuracy than the class one calibrator, so it depends what type of accuracy is needed for the job. The technical specification shows the accuracy levels. Learn More
  2. Class 2 Acoustic Calibrator

    Casella Class 2 Acoustic Calibrator

    £277.20

    This is the Class 2 Acoustic Calibrator, which is very small and housed in a rugged case which makes it easy to transport and keeps damage to a minimum. It is important that the kits are re calibrated before and after the results are taken because the results may be distorted if the meters are not reading correctly and therefore you may not comply to the work regulation standards.
