3B Scientific 1008523 Stefan Boltzmann lamp

1008523 Includes Only:

• 1 Stand rod, 130 mm long
• 1 Stefan-Boltzmann lamp

Stefan Boltzmann lamp. High temperature source designed to Produce thermal radiation, for investigating how such radiation depends on the temperature and to confirm the Stefan-Boltzmann law. The tungsten filament represents a good apProximation of a point source of heat radiation and is thus highly suitable for investigating the inverse square law. The temperature of the lamp can be determined from the resistance of the filament. To minimize voltage loss the lamp contacts are soldered to the connectors.

Features:

• Nominal voltage: 12 V DC
• Nominal current: 1.75 A
• Nominal power: 21 W
• Maximum temperature of filament: 3600 K
