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
