(Optional) Dakks Calibration
Isotech
DAkkS calibration of a standard thermometer in the range -38 ° C to 660 ° C
DAkkS calibration of a working standard thermometer to the
Fixed points of the ITS-90. Achievable measurement uncertainties:
Mercury -38.8344 ° C 3.5mK
Water trip point 0.01 ° C 2.5mK
Gallium 29.7646 ° C 2.5mK
Tin 231.928 ° C 7.0mK
Zinc 419.527 ° C 12mK
Aluminum 660.323 ° C 20mK
The achievable measurement uncertainties depend on the
DUT. Some typical measurement uncertainties can be found at:

The fixed points are determined according to the temperature ranges of the ITS
90 selected. This will be done before the calibration
Working standard thermometer sufficiently aged.
