A common problem found in the industrial metrology is the reliability of
the results obtained from temperature instruments, especially when they are
used in operational processes which effect to the production quality. In this
case, calibration of thermometer associated with a national standard through a
documented unbroken chain of calibrations is of vital importance. This study
presents the reliability of a Pt-100 Platinum Resistance Thermometer (PRT)
measurement results which can be described according to calibration and
statistical methods. The calibrated PRT’s resistance values are characterized
as around 131.00 Ω by making a comparison with a reference PRT at 80 °C bath
temperature and the total uncertainty of the calibration temperature is
determined as ±0.08656 °C by metrological traceability together with
measurement uncertainty. The total uncertainty value changes depending on
uncertainty values of each equipment used in the calibration system.
