Temperature. Liquid-in-glass thermometer, 0 °C to 50 °C
Absolute expanded uncertainty (k = 2, level of confidence 95 %) in °C: 0.13
Comparison in Liquid Bath
Total Immersion LIG, Mercury In Glass, 0.2 °C graduation. The uncertainty is evaluated at measurement points and it is the maximum over the range. The resolution of the UUT component included in the CMC calculation. The uncertainty was evaluated for Total immersion and the resolution of UUT was 0.2 °C. ELC Correction evaluated and included in the UB.
