Description

Zodiac Overseas presents the Stefan’s Constant Apparatus (Closed Model Circuit), specially designed to experimentally determine Stefan’s Constant (σ) using the electrical method. This setup allows students to study the radiation energy emitted by a filament in a thermally insulated enclosure, simulating blackbody radiation behavior.

Key Features:

  • Closed chamber design minimizes heat loss and improves measurement accuracy
  • Fitted with a thermally insulated filament lamp acting as the radiating body
  • Complete with DC power supplyanalog voltmeter, and ammeter for precise input measurements
  • Includes temperature sensor/thermocouple
  • Designed as per academic curriculum for thermal physics experiments
  • Compact, durable, and student-friendly construction

Ideal for physics labs in engineering colleges, universities, and research institutes to experimentally validate thermal radiation principles.
