e) Emissivity
•
Emissivity indicates the energy radiation characteristics of a material.
•
The emissivity of most organic materials and painted or oxidized surfaces is approximately
0.95, which is the default setting of the thermometer.
•
All objects radiate infrared energy, the amount of which is based on the actual surface
temperature of the object and the surface emissivity.
•
The product perceives the infrared energy at the surface of the object and uses this data to
calculate the estimated temperature value.
•
Many common objects and materials (such as painted metal, wood, water, skin, fabrics, etc.)
can effectively emit energy, so it is easy to obtain relatively accurate measurements. For
surfaces that emit energy easily (high emissivity), the emissivity is more than 90% (0.90).
This simplified approach does not apply to glossy surfaces or painted metals, as their
•
emissivity is less than 60% (0.60). These materials emit less energy and are classified
as low emissivity materials. To measure materials with lower emissivity more accurately,
emissivity corrections are required.
•
Adjusting the emission value usually allows the product to calculate an estimate of the actual
temperature more accurately.
