Abstract (Croatian)

Glavni zadatak ovoga rada bio je ispitati termometrijsku komoru za temperaturno područje od -20 °C do 70 °C. Ispitivanje se odvijalo na pet različitih temperatura, a to su: -20 °C, 0°C, 25 °C 50 °C te 70 °C . Postupak ispitivanja obuhvatio je određivanje prostornih temperaturnih gradijenata (prostorne nehomogenosti), vremenske nestabilnosti te dinamike zagrijavanja. Također je određen pojedini doprinos zona ukupnoj mjernoj nesigurnosti umjeravanja termometara. Osim ispitivanja komore odrađeno je i umjeravanje otporničkih termometara u kupkama.

Abstract

The main task of this thesis was to test the thermometric chamber for the temperature range from -20 °C do 70 °C. Testing took place at five different temperatures, which are: -20 °C, 0°C, 25 °C, 50 °C and 70 °C. The calibration procedures included determination of the spatial temperature gradients (spatial inhomogeneity), temporal instability and the heating rate. Individual contributions to the overall measurement uncertainty of thermometers calibration were also determined. Beside the testing of the chamber, calibration of the resistance thermometers was done.
