Calibration services

Fast and efficient calibrations to the highest standard

We calibrate medical instruments globally to maximise the life of the product, check measurement accuracy and compliance to manufacturers and international standards. We endeavour to provide a high level of service with a efficient turnaround time with competitive pricing. We calibrate and support all audiological equipment from leading manufacturers and many other types of medical equipment. We offer a return to base calibration service and an on-site calibration service.

A: Return to base calibration

Send the instrument to Amplivox. A calibration can be completed by one of our trained service engineers and returned to you. If your calibration is urgent please contact our customer services team by via phone on +44 (0)1865 880846 or email.

B: On-site calibration

If needed we can visit your company and calibrate equipment on-site. This is recommended for companies who have many instruments so they can be calibrated at once. Due to high demand, we advise to book on-site calibrations as early as possible in order to meet preferred times.

Frequently asked questions

  • What is audiometer calibration?

    Medical equipment calibration is required to ensure all equipment is in full working to maintain instrument accuracy and to ensure the device is compliant with medical and legal standards. Calibration of an audiometer is a technical process requiring adherence to the relevant standards.

  • When should audiological equipment be calibrated?

    Medical equipment should be calibrated according to manufacturer’s guidelines and legal requirements. These may differ by country and we will support you to ensure you are aware of the requirements. When test results seem to be off expected measurements, a calibration will ensure the equipment measurements are returned to the right standard. This can for example happen when an instrument is dropped or had a sudden shock.

    How long will my calibration take?

    We offer various calibration services to suit your requirements from an on-site calibration to a return to base calibration. When choosing a return to base calibration, your equipment will be calibrated and returned to you in 72 hours of receipt and remains fully insured at all times.

    • Air conduction – ISO 389-1: 2017
