The Pegasus R is a compact furnace for calibrating radiation pyrometers. The temperature of the furnace is set on a controller, whilst an independent indicator, whose sensor fits into the cavity, indicates the actual radiance temperature.
The sensor can be removed for external calibration, or the complete system can be calibrated. The cavity diameter is 20mm, the depth 65mm.Emissivityis0.995. The cavity is removable, and a fixed point cell may be put in its place. The cavity inside the fixed point cell is 10mmin diameter by65mmdeep to the tip of a 120° cone
