Features
- Primary standard fixed points
- Unique patented design
- High accuracy
- Blackbody radiation sources
- Long flat plateau
- ITS 90 fixed points
These cells are used to correlate radiation thermometers to the ITS-90 Scale as well as provide the highest accuracy Blackbody Sources
available. 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.
