[QUOTE="kingofnobbys, post: 1890490, member: 81934"] refer to information : [url=https://www.beardeddragon.org/forums/viewtopic.php?f=34&t=239064&p=1833542#p1833542]viewtopic.php?f=34&t=239064&p=1833542#p1833542[/url] and this explain more : [url=https://www.beardeddragon.org/forums/viewtopic.php?f=34&t=241233]viewtopic.php?f=34&t=241233[/url] It is possible to compensate for emissivity errors but the calculations involved will be beyond most reptile keepers who don't have the necessary physics or engineering education , the existing IR gun is likely 20 to 30 degrees Celsius out when reading the surface temperature the "NON STANDARD SURFACE (which has a emissivity significantly different to the standard e (gun) = 0.95 found with cheap IR guns who have no emissivity adjustment). For those who have some university physics and engineering the brief explanation is as follows : the degree to which errors in emissivity settings will affect temperature and T_error (error in temperature) accuracy even not often understood by many professional physicists , engineers , chemists and thermographers . Little wonder lay people who have no professional training and simply assume the IR gun is going to give accurate temperature readings for all surfaces measured get this wrong . The Stefan-Boltzmann Law gives the radiated infrared energy emitted by a target surface and shows this is exponentially related to the absolute temperature of that surface. The equation is E_b=εσT^4 where ε is the surface emissivity and the true surface temperature is calculated using this equation [img]https://i.postimg.cc/BQ6G8n1t/temperature-emissivity-compensation.png[/img] [/QUOTE]
