Abstract (Croatian)

U sklopu ovog rada provedeno je ispitivanje radijalnih i aksijalnih gradijenata te stalnosti temperature unutar radnog volumena termostatirane kupke Heto KB12 (interna LPM oznaka TEKUP10), koja se koristi za umjeravanje termometara. Ispitivanje kupke izvršeno je korištenjem dvaju neumjerenih termometara, prema internoj metodi Laboratorija. U sklopu izrade završnog rada opisani su postupci ispitivanja termostatirane kupke te korištena oprema. Na osnovi rezultata mjerenja provedenih u laboratoriju, proračunat je doprinos kupke ukupnoj mjernoj nesigurnosti prilikom njenog korištenja za umjeravanje termometara. U radu je također dan tablični i grafički prikaz rezultata provedenih ispitivanja. Na kraju rada su izneseni relevantni zaključci o rezultatima dobivenim ispitivanjem termostatirane kupke.

Abstract

This project is a case study about thermostatic bath Heto KB-12 (internal LPM mark TEKUP10), which is being used for calibration of thermometers. Examination is performed with damp method of unstable temperature variations. Calibration of thermostatic bath, used equipment and research methods are through the thesis elaborated. Results of measurements in the laboratory show certain calibration inaccuracy. Charts and diagrams based on the examination show inaccuracy in due to radial, axial gradients and temperature stability. In addition, relevant conclusions and outlook about the results of examination are presented.
