Calibration of your noise & vibration measurement instruments

Accurate & comprehensive noise & vibration calibration services for any make, model or brand

What we offer and how we can help you

Your noise measurement instruments are a valuable investment and so maintaining the accuracy and performance of your equipment is vital.

Our fixed-price calibration policy gives you a cost-effective way to ensure that you are compliant at all times and that your equipment is kept in peak condition.

Regardless of how often you use your instruments, regular verification by a calibration laboratory is important, as the original manufacturer of your instruments only Cirrus can provide you with the care and attention that you should expect.

In addition to providing for the service and calibration of our own equipment, we can offer both Traceable and UKAS calibration services for a wide range of equipment from manufacturers other than Cirrus. Let us know what you've got and we'll give you a quotation for calibration.

Why is calibration important?

If you are using your noise measurement instruments to meet any Standards, Regulations or Guidelines, it is essential that your equipment is measuring accurately. Most modern standards, regulations of guidelines will clearly state the standards to which the equipment must comply.

For example, the 2005 Control of Noise At Work Regulations states "Your sound level meter should meet at least Class 2 of BS EN 61672-1:2003 (the current instrumentation standard for sound level meters)..", "Your dosemeter should meet the requirements of BS EN 61252:1997 Dosemeters have no type or class number." and "Your calibrator should meet at least Class 2 of BS EN 60942:2003".

and similarly, BS 4142:2014 states: "Select systems for measuring sound pressure levels, including microphone(s), cable(s), windscreen(s), recording devices and other accessories which conform to BS EN 61672-1, Class 1, for free-field application, as appropriate. Filters, where used, should conform to BS EN 61260, Class 1, and sound calibrators to BS EN 60942, Class 1."

If you are going to continue to use your noise measurement instruments over a long period, it is vital that they continue to meet these same standards and this is why calibration, both Field Calibration and Periodic Verification, are an essential part of undertaking noise measurements.
