The Cyclops L family of non-contact portable thermometers introduce several new features to this instrument “dynasty”. … Continue reading

How does a (Noren) heat pipe work?

A “How They Work” Resource from Noren Products Online  —  A heat pipe consists of a sealed aluminum or copper container whose inner surfaces have a capillary wicking material. Inside the container is a liquid (usually alcohol) under its own pressure, and enters the pores of the capillary material, wetting all internal surfaces. Applying heat at any point along the surface of the heat pipe causes the liquid at that point to boil and enter a vapor state.When that happens, the gas picks up the latent heat of the vaporization. The gas, which then has a higher pressure, moves inside … Continue reading

National Physical Laboratory Video Presentations on Temperature Measurements

  New references for high temperature measurements As a culmination of an eight-year research programme an international collaboration has developed robust reference fixed points, studied their sensitivity to impurities and external conditions and finally measured their melting transition temperature. This talk describes how 100+ measurements made by nine different NMIs have been combined to assign low-uncertainty thermodynamic temperatures to the melting transition of Re-C, Pt-C and Co-C metal-carbon eutectics. At the simplest level, these fixed-points will provide new temperature references for the calibration of pyrometers at temperatures above the freezing point of silver (1234.93 K) and will thus reduce the … Continue reading

US National Centers for Environmental Information (NCEI).

Finding Data by Category Online — The demand for high-value environmental data and information has dramatically increased in recent years. To improve their ability to meet that demand, the USA’s former three NOAA data centers The National Climatic Data Center, The National Geophysical Data Center, and The National Oceanographic Data Center, which includes the National Coastal Data Development Center, have merged into the National Centers for Environmental Information (NCEI – www.ncei.noaa.gov/). NCEI is responsible for hosting and providing access to one of the most significant archives on Earth, with comprehensive oceanic, atmospheric, and geophysical data. From the depths of the ocean to the … Continue reading

The most accurate temperature measurements ever made. Probably.

NPL Lecture by Michael de Podesta It is now 25 years since the establishment of the International Temperature Scale of 1990. The scale has been extremely successful in enabling accurate and consistent temperature measurement around the world. However, it has become clear that the thermodynamic temperature estimates on which ITS-90 is based were in error, even at temperatures close to the triple point of water. The discovery and elucidation of this error is largely due to the development of acoustic thermometry. Over the last decade, the development of combined microwave and acoustic resonators for the measurement of the Boltzmann constant … Continue reading
