Return to Base Calibration

At Amplivox we offer a fast and efficient in-house calibration service for audiological equipment. Products returned to us will be calibrated / serviced and sent back to you via our carrier.

On-Site Calibration

We offer an all-inclusive on-site calibration service where we come to you to calibrate and service your equipment. This will save you the time involved sending the equipment and being without it for a few days. We highly recommend that you book your on-site calibration a couple of months in advance to ensure that we fit you in to your schedule.
