Page 9: Introduction
2 Introduction The M310-HT is a portable blackbody calibration source utilizing a digital indicating temperature controller that may be set to any temperature between ambient temperature to 450 °C (842 °F). A precision RTD temperature sensor is embedded in the blackbody emitter providing high accuracy and repeatability. -

At 250 °C, this pyrometer will read 251.4 °C or 1.4 °C high, so you should set the blackbody setpoint to 248.6 °C (250-1.4). M310-HT Manual Appendix A: Calibration & Emissivity • 21...
- Page 22 Example 2: The M310-HT (450 °C) blackbody was factory calibrated to provide effective emissivity = 1.0 at 8-14 µm. You wish to use this source for an imager that has spectral response of 3-5 µm. The mean value between 3-5 µm from the graph above = 0.943. The blackbody exit radiance at 3-5 µm will be approximately equivalent to a blackbody that has emissivity = 0.943.

Page 23: Using The M310 To Calibrate "Fixed Emissivity" Pyrometers
(infrared thermometers) that have fixed emissivity at 0.95 (and operate at 8-14 µm wavelength). This table assµmes the ambient and background are at 23 °C. If your pyrometer has adjustable emissivity, do not use this table and set your pyrometer emissivity to 1.0. M310-HT Manual Appendix A: Calibration & Emissivity • 23... -
Page 24: Background Influence On Apparent Emissivity
When emitter emissivity is less than 1.0, the background energy times (1-emissivity) reflects to the device under calibration. For this reason, the M310-HT may appear to have a higher “apparent emissivity” near ambient than when operated at higher temperatures. -
