Calibration Information


We offer two types of calibration, Traceable and UKAS. All of our calibration equipment is tested and traceable to national standards and the calibration process is carried out following documented procedures. 

Our calibration laboratory works on all makes and models of equipment, offering swift turn around without compromising accuracy. Our labs have a range of calibration equipment, from our dedicated tapping machine test area to our anaechonic chamber, perfect for testing microphones at all levels. All calibration is undertaken in a quality controlled environment to ensure that published uncertainties are maintained.

We are able to provide - Verification of dodecahedron loudspeaker directivity in accordance with ISO 16283-1, Annex A.  Requires matched power amplifier.

We are also UKAS accredited to calibrate the following equipment:

  • Sound Level Meters
  • Vibration Calibrators
  • Tapping Machines
  • Sound Calibrators
  • Microphones



FAQ's for calibration

How long does calibration take?

We work on an 5 -7  working day turn around period, however this can fluctuate during busy periods. Please ask for our current turn around when you contact us for calibration.

How do I get my equipment to you?

We offer a 48 hour collection and return carriage for the fixed price of £35.00 on all calibration work.

How much does calibration cost?

Prices vary depending on your choice of calibration and what it is you are having calibrated. For a full and accurate quote please contact our team who can provide you with a personalised quote.

Are there choices of calibration?

We are proud to be able to offer UKAS calibration of several types of equipment, alternatively we also offer a fantastic traceable calibration which is tested against national standards.

What equipment do we calibrate?

We calibrate a vast range of equipment, if you are unsure if we would calibrate yours please contact us to find out. If we can't help we will always try our best to suggest someone that can.

Do we repair equipment?

We do offer a repairs service, if your equipment needs repairs please give our technical sales team a call today to discuss.

I've lost my certificate; can you send me a copy?

To provide duplicate certificates/results we must interrupt the normal calibration workflow to reload the instruments stored data onto the calibration system. To that end, if you need a replacement PDF copy we do charge £20 which we will then send to you via email.

How often should I get my equipment calibrated?

Under the normal noise measurement standards, the maximum calibration interval for test equipment is:

  • Sound Level Meters – every 24 months
  • Sound Calibrators – every 12 months

These periods are the recommended maximum intervals but it is the user’s responsibility to decide the calibration interval for each piece of equipment. Most customer’s stay with these recommended periods.
