Abstract (Croatian)

U sklopu ovog rada provedena su ispitivanja aksijalnih i radijalnih gradijenata te temperaturna stabilnost u radnom prostoru termostatiranih kupki: 1.Kambič OB-50/LT-2 – s etanolom (u temperaturnom području -30°C do 10°C) Kambič OB-50/LT-2 – s vodom (u temperaturnom području 20°C do 80°C) 2.Isotech 915LW – s etanolom (u temperaturnom području -60°C do 20°C) Ispitivanje kupki izvršeno je korištenjem dvaju odnosno triju termometara prema internoj metodi Laboratorija. U sklopu završnog rada biti će detaljnije opisani pojedini postupci ispitivanja te navedena mjerna oprema korištena pri samim ispitivanjima. Na osnovi rezultata mjerenja provedenih u laboratoriju, proračunati su doprinosi pojedinih kupki ukupnoj mjernoj nesigurnosti prilikom 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 termostatiranih kupki.

Abstract

This works is about examination of axial and radial gradients and temperature stability of thermostatic baths: 1.Kambič OB-50/LT-2 – ethanol (temperature range -30°C to 10°C) Kambič OB-50/LT-2 – water (temperature range 20°C to 80°C) 2.Isotech 915LW - ethanol (temperature range -60°C to 20°C) Baths examination was carried using two or three thermometers according to internal Laboratory method. As part of this work measuring procedures and used equipment will be precisely described. Based on examination results, contributions of individual baths are calculated to total measurement uncertainty when calibrating thermometers. 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.
