What is Testo Calibration?

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 and technology to ensure we complete your calibration within five business days.

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. As we store your calibration certificates on our secure server we can always send you a replacement copy. If you require your instrument to be calibrated to a special standard (NATA), please contact our service department. All our calibration experts are specially trained on our range of Testo instruments and are available to answer your questions.

What is included in a Testo calibration?

 Calibration Check - Comparison of an analyser’s output signal (measured reading) to a known standard.

 Calibration Adjustment or Span (where possible) - To adjust the measured reading to the smallest possible deviation according to the known standard value or reference. Therefore, adjustment requires a change of the instrument settings.

 Error of Measurement (Accuracy) - Indicated measurement minus the true value of the measured variable.
