and Language Selection can be found in the menu. Each setting is saved after
change and will be kept even the SenXorProViewer App is restarted.
Emissivity is a property of the material of each individual object in the field of
view. It quantifies the ability of an objects surface to emit long-wave infrared
radiation and strongly affects the temperature readout from the IR203. By
default, the emissivity is set to 0.95 which is a representative value for many
common objects with matt surface, as well as the human skin (in the range of
0.95 - 0.97). Note that metals tend to have a dramatically lower emissivity as
low as 0.1, and it trongly depends on their surface processing. The user can
adjust the emissivity according to the exact object of observation.
