    IR Measurement Notes 1. The object under test should be larger than the spot (target) size calculated by the field of view diagram (printed on the side of the meter and in this guide). 2. Before measuring, be sure to clean surfaces that are covered with frost, oil, grime, etc. 3.

  • Page 20: Emissivity And Ir Measurement Theory

    Emissivity and IR Measurement Theory IR Thermometers measure the surface temperature of an object. The thermometer’s optics sense emitted, reflected, and transmitted energy. The thermometer’s electronics translate the information into a temperature reading which is then displayed on the LCD. The amount of IR energy emitted by an object is proportional to an object's temperature and its ability to emit energy.
