Abstract

The objective of this paper is to present the methodology for estimation of measurement uncertainties in comparison calibration of thermocouples used at Laboratory for Process Measurements (LPM). The methodology is applied for comparison calibration of rare-metal and industrial basemetal thermocouples within temperature range from –20°C to 660°C with LPM standard/working standard platinum resistance thermometers and from 600°C to 1050°C with LPM standard/working standard thermocouples.
