Page 64: Ppendix How Infrared Thermometry Works
ppendix: How Infrared Thermometry Works Thermal Radiation Heat is transferred from all objects via radiation in the form of electromagnetic waves or by conduction or convection. All objects having a temperature greater than absolute zero (-273°C, -459°F, 0 K) radiate energy. The thermal energy radiated by an object increases as the object gets hotter. - Page 65 ppendix: How Infrared Thermometry Works Blackbody When thermal radiation falls on an object, part of the energy is transmitted through the object, part is reflected and part is absorbed. A blackbody is defined as an ideal object that absorbs all the radiation incident upon it.
- Page 66 ppendix: How Infrared Thermometry Works Wien’s Displacement Law describes the exact mathematical relationship between the temperature of a blackbody and the wavelength of the maximum intensity radiation. where λ = wavelength measured in microns T = temperature in Kelvin Calculating Temperature The net thermal power radiated by an object has been shown to depend on its emissivity, its temperature and that of the ambient temperature around the object.
- Page 67 ppendix: How Infrared Thermometry Works Optics Field of View Accurate measurement of temperature via infrared means depends strongly on the size of the object and the distance between the thermometer and the object. All optical devices (e.g. cameras, microscopes, infrared thermometers) have an angle of vision, known as a field of view or FOV, within which they see all objects.

0.95. For this reason, we use 0.95 as the default emissivity setting in the OS550A Series thermometers. For objects of unknown material or for very precise measurements, use one of the following methods to determine a specific emissivity value. - Page 71 ppendix: Determining an Unknown Emissivity Method 3 Use this method to measure objects at temperatures below 500°F (260°C). Place a large piece of masking tape on the object (or at least a sample of the object material). llow time for the masking tape to reach the object temperature.
