Comparison of the Calibration of Liquid-in-Glass Thermometers in the Range from-30 degrees C to 150 degrees C

摘要

MIRS/UL-FE/LMK and MBM organized a bilateral comparison of a set of liquid-in-glass thermometers (LIGTs) in the range from to . The circulating items were three total immersion LIGTs, manufactured by Thermo Schneider, resolution of , covering range from to (Serial Number 991289), to (Serial Number 9710425), and to (Serial Number 991308). The range between and has been already compared in another interlaboratory comparison. This interlaboratory comparison was also registered as EURAMET 1249 comparison project (comparison of the calibration of liquid-in-glass thermometers in the range from to ). The results of the comparison showed that all 18 pairs of measurements performed by the participating laboratories agree within declared uncertainties and thus supported declared calibration and measurement capabilities by MIRS/UL-FE/LMK and MBM.
