Stefan Boltzman Apparatus  Name
(Code - ALABS-A143-029 ) | Altec Export Lab Specification:
Stefan Boltzman Apparatus :   Stefan Boltzman Apparatus
  • The apparatus is designed to determine the Stefan Boltzman constant.
  • The apparatus consists of a hemisphere fixed to a Bakelite plate, the outer surface of which forms the jacket to heat it.
  • Hot water to heat the hemisphere is obtained form a hot water tank, which is fixed above the hemisphere. The copper test disc is introduced at the center of hemisphere.
  • The temperatures of hemisphere and test disc are measured with the help of temperature sensors.
  • Determination of Stefan Boltzmann constant and study the effect of hemisphere temperature on it.
Utilities Required:
  • Electricity Supply : 1 Phase, 220 V AC, 2 kW.
  • Table for set-up support.
