Isotech 970 Pegasus R Blackbody Source

A compact furnace for calibrating radiation pyrometers, the Isotech Pegasus R blackbody source sets the temperature of the furnace on a controller while an independent indicator, whose sensor is built into the furnace’s cavity, indicates the actual radiance temperature. The Isotech Pegasus R blackbody source has a cavity diameter of 0.8″ (20mm) and a cavity depth of 2.6″ (65mm). The emissivity is 0.995. The cavity is removable and a fixed-point cell may be put in its place.

A Blackbody Target Radiation Source is housed within the Isotech Pegasus R blackbody source for the calibration of radiation thermometers in the wave-length range of 9 to 14 micrometers. Incorporating suitable insulation within its design, this radiation source’s aperture is 0.4″ (10mm) in diameter. A scan across the aperture at 444°C demonstrates the source is uniform to better than 0.3°C. A calibration certificate is available for the built-in indicator and supplied probe.

The Isotech Pegasus R blackbody source’s temperature range is 150 to 1200°C, and it has a stability of 0.1°C. Time to temperature is 20 minutes. Weighing only 15 pounds, the Isotech Pegasus R blackbody source is easily carried in the field for on-site use.

The Isotech Pegasus R blackbody source can be supplied with either RS232 or RS422 communications.

Cal Notepad software now comes standard with the Isotech 970 Pegasus R Blackbody Source. Cal NotePad Software automatically logs and displays the temperature of an Isotech calibration bath together with the sensor under test. Cal Notepad can be used with baths (or indicators) without PC interfaces by the user typing in values from the keyboard.
