Appendix A: Calibration & Emissivity

Using the M310 to calibrate “fixed emissivity” pyrometers

For convenience, the table below shows what setpoint to use when calibrating 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.
