Abstract

The Temperature Metrology Laboratory of Puslit KIM-LIPI has been able to develop a platinum resistance thermometer Pt 2.5. This thermometer can be used in a temperature range (0 ~ 100)°C. It is calibrated using Pt-25 standard platinum resistance thermometer. The calibration result shows that the thermometer has uncertainty 0.22°C with a confidence level 95% and coverage factor k = 2. It meets resistance thermometer accuracy for class B, in a temperature range of use (0~70)°C based on standard DIN EN 60751:2009. Keywords: platinum resistance thermometer, performance test
