Servicing & calibration

Calibration & servicing of your noise measurement equipment

Your noise measurement instruments are a valuable investment and so maintaining the accuracy and performance of your equipment is vital, especially if you need to meet any regulations, standards or guidelines, e.g. the Noise at Work Regulations.

Regardless of how often you use your instruments, regular calibration is an important part of this and as the original manufacturer of your instruments, only Cirrus can provide you with the care and attention that you should demand.

Our fixed price calibration policy gives you a cost effective way to ensure that you are compliant with any regulations and that your equipment is kept in peak condition.

Supported by our 15 Year Warranty

Cirrus offers new products with a two year return to base warranty against all faults. This warranty is extendable, one year at a time, up to a maximum of fifteen years, if the products are calibrated annually with Cirrus Research plc or a Cirrus Calibration Centre.

In short, if your instrument is calibrated annually with Cirrus, then you can enjoy peace of mind for up to 15 years, through our industry leading "no quibble" warranty policy.


Calibration of your equipment

The Cirrus Research plc Calibration and Service department provides calibration and repair services for the entire Cirrus noise measurement product range with fully trained engineers with many years experience in our industry. They are backed by our R&D team who design the instruments and whose knowledge of Cirrus products and noise measurement technology is second to none.

Our company including the Calibration and Service department is covered by our ISO 9001:2008 certification with measurement traceability direct to the UK National Physical Laboratory (NPL).

Our policy is to levy a fixed charge for service and calibration which will cover your instrument so you can be sure of the costs involved in maintaining your instrument to the highest standard.

We can provide you with a traceable calibration facility as well as repair and servicing if your instrument is not working correctly. If you have any questions, please contact us and we will be pleased to help.

Fixed price repairs

If your Cirrus instrument needs to be repaired, we can offer a fixed price repair which will cover putting the instrument back into working order. This excludes damage to microphone capsules and instrument displays or if the instrument is beyond economic repair. In these circumstances we will contact you to let you know of any additional costs.
