Isotech<\/a> Medusa R is a versatile blackbody source designed for calibrating infrared thermometers across the temperature range 30 \u00b0C to 550 \u00b0C. With its deep cavity, high emissivity and excellent temperature uniformity, the Medusa R provides a stable and repeatable radiation field suitable for both industrial and laboratory applications.<\/p>\nHigh emissivity and deep cavity<\/h3>\n
The Medusa R features a 45 mm diameter, 285 mm deep cavity engineered to produce a uniform radiating surface. With an emissivity of >0.995, the source behaves as an almost ideal blackbody, enabling low\u2011uncertainty calibration of IR instruments.<\/p>\n
Compatible with large ITS\u201190 fixed\u2011point cells<\/h3>\n
For the lowest uncertainties, the Medusa R can be used with Isotech ITS\u201190 fixed\u2011point cells, including:<\/p>\n
\n- > Indium (156.5985 \u00b0C)<\/li>\n
- > Tin (231.928 \u00b0C)<\/li>\n
- > Zinc (419.527 \u00b0C)<\/li>\n<\/ul>\n
These large primary cells fit directly into the deep cavity and are supplied with metal\u2011purity certificates, making the Medusa R suitable for traceable high\u2011accuracy IR calibration.<\/p>\n
Stable performance and precise control<\/h3>\n
The Medusa R offers:<\/p>\n
\n- > Stability: \u00b10.1 \u00b0C<\/li>\n
- > Emissivity: >0.995<\/li>\n
- > Display resolution:<\/li>\n<\/ul>\n
\n- > 0.01 \u00b0C from 30 to 99.99 \u00b0C<\/li>\n
- > 0.1 \u00b0C from 100 to 550 \u00b0C<\/li>\n<\/ul>\n
The heating time is approximately 45 minutes, making the system practical for routine calibration work.<\/p>\n
Distributed heating for excellent uniformity<\/h3>\n
The large block is heated using distributed heating technology, minimising temperature gradients and ensuring a calm, uniform radiation field \u2014 essential for accurate comparison and verification of IR instruments.<\/p>\n
Compact, robust and easy to use<\/h3>\n
The Medusa R includes:<\/p>\n
