Оцінювання невизначеності вимірювань при калібруванні засобів вимірювання вологості повітря

Abstract

The problem of estimating the uncertainty of measurements of relative air humidity measuring instruments is considered. An expression for deviations of hygrometer readings from values specified by a standard humid gas generator is written. Input quantities and their standard uncertainties are estimated. The calculation of the combined standard and expanded uncertainties when calibrating a hygrometer is performed. A measurement uncertainty budget is compiled.
