New Gallium Fixed Point Cell for the Hyperion R

New Gallium Fixed Point Cell for the Hyperion R

8 Jun 2020

The Hyperion R Portable Blackbody Calibration Source allows for calibration of non-contact infrared thermometers over the temperature range -10°C to 80°C. Laboratory performance and low uncertainty calibrations are ensured by the combination of high emissivity and excellent temperature uniformity.

Following requests from researchers looking to improve the accuracy of infrared measurements, we have introduced a Gallium Fixed Point Cell, Model 982-05-01. The cell contains high purity Gallium, 99.99999% (7N). The cell is placed into the Hyperion R cavity and heated until the metal melts at 29.7646°C. As the Gallium melts, the temperature remains constant with the “melt plateau” providing a stable, precise constant reference temperature.

After all the metal has melted, the cell can be simply frozen by lowering the Hyperion R temperature, no additional equipment is necessary.

For higher temperatures Isotech have the Gemini R, Medusa R and Oberon R. The range of temperatures available are at fixed points from Gallium to Copper.
