Description:

• Computerized Emissivity Measurement Apparatus offers basic experiments for targeted teaching on the topic of heat transfer by radiation.
• The reflector concentrates the radiation to a focal point.
• A sample is placed on a thermocouple located at the focal point.
• The thermal radiation emitted by the sample is measured by a thermopile.
• At the heart of the experimental unit is a metallic sample heated by a concentrated light beam.
• The light beam is generated by a continuously adjustable halogen lamp and a parabolic reflector.
• In order to be able to measure the radiation at different distances, the thermopile is mounted on a moveable carriage.
• Heat radiation is one of the three basic forms of heat transfer.
• In radiation the heat transfer takes place via electromagnetic waves.
• Unlike heat conduction and convection, heat radiation can also propagate in a vacuum. Heat radiation is not bound to
