Primary Standards
Optimal ITS-90 Fixed PointsLarge ITS-90 Fixed Points for the Primary Laboratory, no compromise design for the smallest measurement uncertainties.
Metrology FurnacesA range of furnaces for the realization of ITS-90 Fixed Points and for annealing of SPRTS. Temperature ranges from 50 to 1300ºC.
Slim ITS-90 Fixed PointsA range of smaller Fixed Point Cells and Apparatus providing affordable absolute calibration from the Mercury to Silver Points.
ITS-90 Isothermal TowersRobust, easy to use integrated devices that allow ITS-90 Fixed Points to be realised, combining a heat pipe and cell into a single piece of apparatus.
SPRTs & TCsA range of long stemmed SPRTs for the Primary Laboratory covering the range -200 to 1000ºC and Noble Metal Thermcouples to 1600ºC.
