Calibration Services
Guymark’s audiological calibration service is a total equipment check
Our calibration 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 – any repair work will be quoted separately. We keep a database on the history of your product – to make sure our service engineers know your equipment inside out. We are dedicated to sustainability by providing digital certificates for all calibrations.

Calibration Contracts
We offer three and five year calibration contracts either at your premises or for items returned to our laboratory. You can have a contract for a single item or a whole department.
A contract means you get a fixed price for the three or five years – a quantity discount can be offered based on the number of instruments being calibrated.
For on-site calibrations we will remind you when your calibrations are due and offer ‘guaranteed service dates’ – where we allocate your service time for the term of your contract.
Once your calibrations have been completed you will receive copies of the calibration certificates and service reports. Our reports will also detail any recommendations for repair or replacement of the equipment as necessary.
