Experimental Set Up has been designed specifically for measuring Determination of Stefan's constant σ (black body radiation).
The set up is absolutely self contained and requires no other apparatus.
Practical experience on this set up carries great educative value for Science and Engineering Students.

Object
Determination of Stefan's constant σ (black body radiation).
