IMPROVING HUMIDITY MEASUREMENTS IN METEOROLOGY

A product with a unique advantage Air humidity and temperature play an important role in meteorology. Highly accurate measurements of these climate parameters form the basis of accurate forecasts and meaningful records. The E+E Elektronik Model EE33 series humidity and temperature sensor is the only one on the market with a double-heated probe. Both the sensor tube and the sensor element are heated. An application note, free for download from their website, tells the rest of the story. You can download it be clicking here. If that does not work, as sometimes happens when organizations “refine” their websites, we have … Continue reading

Thermocouple calibration at NPL – Supply of cobalt-carbon eutectic fixed point

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. For more information visit the NPL webpage … Continue reading
