This apparatus allows the demonstration of the dramatic differences in radiated heat from various surfaces. Being electrically heated it is more convenient than some of the more conventional methods involving water or Bunsen flames.
The apparatus contains a single aluminium plate divided into 3 different regions: a matt black section, a polished aluminium section and a roughened aluminium section. The plate is heated using a resistive element, ensuring that each section is at the same temperature. Readings of each surface may then be taken using an infra-red thermometer (not supplied). Connection to power supply is via 4mm sockets.
The plate requires an adjustable 12V D.C. power supply capable of providing 1A continuously.
