THERMAL RADIATION.
GENERAL DESCRIPTION
The apparatus is a bench top unit is used for studying the laws of heat transfer by radiation using two alternative energy sources namely a radiant heat source and a light source.
The radiation sources as well as accessories are mounted on a horizontal aluminum profile base frame with track scale.
The radiant heat source employs a heater in a housing. Temperature of the heat source can be controlled. Heat radiation is measured by a radiometer. Metal plates with different surface finishes are fitted with thermocouples to demonstrate effect of emissivity on radiation emitted and received. An adjustable vertical slot aperture plates are also provided to study area factor.
The light source is provided by a lamp in a housing with a glass diffuser. Measurement of light is by a light meter. Filters of varying opacity are supplied.
A service module provides power supply and heater control, temperature indicators and radiometer indicator.
