(0 °C up to 1600 °C) Teddington, UK – The UK’s National Physical Laboratory (NPL) offers a UKAS-accredited thermocouple calibration service (laboratory number 0478) for platinum-rhodium thermocouples using freezing points of zinc, silver and copper (up to 1100 °C) and the melting points of gold and palladium (up to 1600 °C). (Type B thermocouples are [...]
Calibration
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 [...]

About a unique Triple Point Cell based on Ethylene Carbonate developed at Britain’s National Physical Laboratory (NPL) in a nearly 4 minute video from YouTube. It’s kind of a commercial, but a really useful one. It explains about this special calibration tool and how it can and is being used to help verify the calibration [...]
From Fluke Corporation In this video Matt Newman from Fluke Corporation’s Hart Scientific Division (www.HartScientific.com) demonstrates the proper technique for realizing a triple point of water cell for temperature calibration. Triple point of water cells are used for calibrating a variety of precision thermometers. The triple point of water cell is an intrinsic standard with [...]
