Basic Knowledge of Non-Contact Thermometers
What is Transmittance?
Amount of Infrared Ray Transmitted by Objects
Transmittance is the proportion of infrared energy that passes through an object.
-
Glass/Film
Object with high transmittance
Affected by the temperature of the background -
Rubber
Non-transparent object
Stable temperature measurement is possible
|
Low transmittance minimizes the effects of the background temperature, allowing for stable temperature measurement. |
When measuring glass or film, using a thermometer specifically designed for glass or film allows measurement without being affected by the background.
