For calibration of thermocouples (1324 °C)
Teddington, UK — The UK’s National Physical Laboratory (NPL) now offers for sale the novel cobalt-carbon eutectic fixed point for thermocouple calibration with ultra-low uncertainties at 1324 °C.
The melting point cell consists of a high purity graphite crucible containing an ingot of cobalt-carbon alloy constructed from cobalt and carbon each having a purity of at least 99.999%.
The cells are supplied with an NPL certificate showing the melting temperature (uncertainty ± 0.55 °C, k = 2) of the cell determined, traceable to ITS-90, by radiation thermometry.
