hallo to all,

Trough a datalogger i get those measurements in Volt
i am able to convert the Volt back in the temperature but in Radiation it is more difficult
i found the plancksche function, but i do not really understand that

can anybody help me?

best regards

If the target is a black body, then the radiation only depends on the temperature and surface area. If you know the temperature, then plug it into Planck's law to get the brightness (as a function of wavelength or frequency).

It is a Pyrometer from Heitronics, KT19.XX Series

My target is not a black Body, for testing i measure now in the Office the door/wall. Later it will be used to measure Vegetation.
I´m also not sure wich emissiongrade i should set. Can i use planck`s law, although i measure not a black Body? Is the function the same?

Thank you guys so much!

Best regards
