Calibration Services

Our dedicated, experienced and fully trained team is focused on providing you with the support you need to continue working efficiently and effectively with our calibration services.

Calibration to suit your business needs

We offer two ways to have your instrument calibrated:

A: Return to Base Calibration

Our fast in-house calibration service is suitable for all types of audiological equipment, simply send your product to us with the completed forms.

The majority of calibrations are completed and returned to customers within a working week at a highly cost-effective price.


Did you know that we support and calibrate more brands than just Amplivox? Get in touch with our Support team to find out more.


B: On-Site Calibration

To save you the time of sending your audiological equipment to us, and being without it for a few days, we are happy to come to you!

Due to a high demand, we recommend that you book your on-site calibration as soon as possible to ensure we fit into your schedule.
