2 Introduction
2.1 Description
The blackbody calibration source features a unique uniformly heated spherical cavity with a
near ideal emissivity of 0.999 or better. The M300 will deliver any temperature between 200 °C
and 1150 °C. A convenient microprocessor based, self-tuning digital PID controller holds the
selected temperature to within 1 °C, assuring high accuracy calibration of infrared
thermometers, thermal imaging equipment, etc.
