Calibration Services

Guymark’s audiological calibration service is a total equipment check.

Our service includes an initial functional test to the maker’s specification, followed by medical electrical safety testing and labelling of all attached transducers to ensure traceability and validity of calibration. We carry out performance checks which include linearity and total harmonic distortion. We valet every part of your instrument including leads, cables, connectors, headbands, control knobs and buttons. Our service engineers can also give advice and assist with any concerns you may have with the performance of your equipment. All of these services are included in the price – you only pay extra if spare parts are required.

We will send you a reminder a month before calibration is due – and can provide paperless documentation if required. We keep a database on the history of your product – to make sure our service engineers know your equipment inside out.
