• Abstract:

  When using an instrument, it is necessary to know the uncertainty of the measurement performed, which is an important variable for the quality and safety of a process. In this sense, this work develops a tool that aims to measure the measurement uncertainty of an instrument, as well as to facilitate a possible calibration process. However, since there are differences according to the instrument to be evaluated, it was necessary to make a cut, and the worksheet developed in this work is specific for analog manometers. The methodology of this work is based on the ISO GUM method, and the spreadsheet was developed using Microsoft Excel software. The developed spreadsheet met the proposed requirements, being a simplified way to calculate the uncertainty of a manometer. It was also noticed that the spreadsheet has didactic potential, being not only a way to check the results, but also to carry out instrument calibration practices in a faster and more assertive way.
