From this Article:
The advantage of fixed point calibration is the small uncertainties associated with the method. The very pure fixed point substance can be melted or frozen to produce an absolute temperature for...

From this Article:
One major problem that keeps recurring is the request to calibrate, or in some other way to evaluate, very short industrial temperature sensor assemblies. These sensors are so short that the sensor...

From this Article:
The most accurate measurements made in a Primary Temperature Laboratory are during intercomparisons of ITS-90 fixed point cells, and in particular intercomparing water triple point cells. To assess...

From this Article:
The production of isothermal volumes of known temperature is the essence of both fixed point and comparison calibrations. The uncertainty of comparison calibrations is made up from: 1. The uncertainty...
