Comparison of the calibration of liquid in glass thermometers in the range -30 °C to 150 °C

Project Description

The purpose of the comparison is to compare the results of the participating laboratories during calibration of a liquid in glass thermometers (LIGTs).

The circulating item are three liquid in glass thermometers, manufactured by Thermo Schneider, resolution 0,1 °C, covering range from -30 °C to 10 °C (serial number 991289), 0 °C to 50 °C (serial number 9710425), 100 °C to 150 °C (serial number 991308). The diameter of the thermometers is Ø 5 mm and they are total immersion liquid in glass thermometers.

It is recommended that the participants use their standard procedure during the temperature calibration and if possible avoid making extra time-consuming measurements.
