Isotech Gemini R Blackbody Source

Isotech Gemini R Blackbody Source

The Isotech Gemini R Blackbody is a portable calibration source and provides calibration of non-contact infrared thermometers in the temperature range from 30°C to 550°C. It is suitable for use as a primary radiation source for infrared thermometers. Laboratory performance and low uncertainty calibrations are ensured by the combination of high emissivity and excellent temperature uniformity. The digital temperature controller allows the block temperature to be set from 30°C to 550°C.

Traceability of the radiation temperature is determined by a separate, built-in temperature indicator and recorded platinum resistance thermometer.

For the smallest uncertainties, the Gemini R can be used with Isotech ITS-90 Fixed Point Cells, gallium 29.7646°C, Indium 156.5985°C, Tin 231.928°C and zinc 419.527°C. The cells are provided with a certificate of metal purity.

SHORT INTRODUCTION BLACKBODY

A blackbody is defined as a source with zero reflectivity or a source that emits the maximum possible radiation (at all wavelengths) for its temperature.

EMISSION POTENTIAL

Emissivity is the ratio between the radiation emitted by a surface and the radiation emitted by a blackbody at the same temperature. Isotech has a range of sources with high emissivity combined with thermal uniformity for use as Primary Standard Sources for independent wavelength calibration with low uncertainty.
