Determining the accuracy/measuring uncertainty

The entries for the measuring uncertainty for the probe are
determined in accordance with GUM (Guide to the Expression of
Uncertainty in Measurement/DIN V ENV 13005).
All parts that make up the measuring uncertainty given by Testo
are listed below. When comparing the measuring
uncertainty/accuracy between manufacturers, which components
are included is to be taken into account. In many cases, not all
elements that contribute to measuring uncertainty are assessed, for
