Isotech has worked with the world's leading suppliers of infrared temperature measurement equipment, national labs, and industry professionals to develop an outstanding range of Black Body Fixed-Point Cells. These infrared standards are used to correlate radiation thermometers to the ITS-90 Scale, as well as to provide the highest accuracy Blackbody Sources available.

There are three ranges for our blackbody radiation source cells: 1. Our primary cells, used with our large apparatus, the Medusa or Oberon, and Medium and High Temperature Secondary Cells. 2. The Medium-Temperature Cells slide into our Gemini R apparatus. 3.The High Temperature Cells work with our Pegasus R model.

All Cells contain 99.9999% pure metals, and will provide a melt or freeze curve to within ±0.01°C. The Primary Cells used in our larger sources will provide significantly longer plateaus.

The results, as seen by a radiation pyrometers, which are slightly sensitive to wall temperature, give uncertainties of better than ±0.25°C.

Easy replacement allows one apparatus to work with multiple cells.
