STEFAN BOLTZMANN APPARATUS (HT-28)

S P Tech Equipments has designed the Stefan Boltzmann Apparatus to determine the Stefan Boltzmann constant. The apparatus consists of a Hemisphere fixed to a Bakelite plate, the outer surface of which forms the jacket to heat the hemisphere. A test specimen in the form of copper disc is placed at the center of hemisphere. Hot water obtained from heater in hot water tank is used to heat the hemisphere. The temperatures of hemisphere and test disc are measured with the help of thermocouples. A timer is provided to measure the temperature of disc at the fixed interval.
