970 Blackbody IR Temperature Calibrator. Temperature 150° C to 1200° C
Calibrates Radiation Pyrometers: 150° C to 1200° C
A compact furnace for calibrating radiation pyrometers, the Pegasus R 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 cavity’s diameter is 0.8” (20mm).
The depth is 2.6” (65mm).
The emissivity is 0.995. The cavity is removable and a fixed-point cell may be put in its place.

Pegasus R Blackbody Temperature source

Model  Description 
970  Pegasus-R High Temperature Blackbody source
High Temperature Radiation Pyrometer Primary Source
0.995 Emissivity
Accepts Fixed Point Cells
NIST Certificate: For the built-in Indicator and supplied probe
A Blackbody Target Radiation Source is housed within the Pegasus R 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.
Traceability may be established with a NIST certificate for the built-in indicator and supplied probe.
The Pegasus R’s temperature range is 150°C to 1200°C and it has a stability of 0.1°C.
Time to temperature is 20 minutes. It weighs only 15 lb. and is easily carried in the field for on-site use.
The Pegasus R can be supplied with either RS232 or RS422 communications.
