Contact thermometry services
All of our routine thermometer calibration services are listed below. If you have requirements outside our routine range, require advice, or require field measurements contact Rod White.
For all routine calibrations, please contact Hamish Edgar to arrange a mutually suitable date for the calibration before shipping your thermometer or bridge to us. This will help us to ensure that your packaging is satisfactory, that we understand your requirements, and that we minimise the time you are without your instruments. When you are ready to ship, use this address label (PDF 119KB).
