The Isotech Pegasus 4853 dry block calibrator offers extreme high temperature calibration in an easy to use portable package, ideal for the calibration of high temperature thermocouples. It has been designed for fast heating and finds applications in the glass, electrical power, automotive and material processing industries.

A Blackbody target can be added for the calibration of infrared thermometers. It is used with a specially angled Type R thermocouple that sits immediately behind the target area. The standard insert has four 8mm pockets 80mm deep. The metal insert is strategically placed beneath 50mm of insulation to provide optimal performance over the radiant temperature range.

The Pegasus comes in three models, Basic, Site, and Advanced. The Basic has a digital display of set and nominal temperature, the Site additionally includes a built-in independent temperature indicator for a reference probe. The Advanced controller has inputs for reference and test thermometers with a further range of sophisticated features including automatic temperature cycling, secure data logging and full color high resolution display.

The calibration volume is 33.5mm diameter by 130mm deep, with a heating rate of 25°C per minute. Cooling time from 1200 to 200°C is 180 minutes, which can be substantially reduced with the optional cooling adapter.
