Calibration & validation services

Ensure accuracy. Service and calibrate regularly.

Calibration involves a comparison of readings between the instrument being calibrated and the reference instrument (also called reference standard) in specific conditions. Other important aspects of calibration include documenting any deviation recorded, calculating and recording the resulting measurement uncertainty, adjusting the results to comply with the reference where possible and creating the calibration certificate. 

The Testo calibration lab has state of the art reference equipment to ensure we complete your calibration within ISO guidelines.

Additionally, we have an automated system that registers your instrument history and sends you a reminder email when your instrument is due for its next calibration. 

If you require your instrument to be calibrated to a special standard (NATA) please contact our service department. 

We also offer on-site service and calibration to all our customers based in Victoria, please contact our service department for more information 

All our calibration experts are specially trained on our range of Testo instruments and are available to answer your questions.
