The equipment has two parts; an aluminium Experiment Frame and a Control Box. The frame holds all the experiment parts and allows the user to slide the parts along easily for experiments of transfer over distances. The Control Box contains the electrical controls and displays of the measured readings.
The user fits different parts to the frame to measure the radiant transfer from light and heat sources.
The heat source uses a variable low-voltage electric heater on a flat plate, creating a black body heat source of variable temperature. A thermocouple measures the heat source temperature. A moveable thermopile measures the heat radiation from the heat source at varying distances. TecQuipment include plates with different apertures, surface finishes and thermocouples. They allow extra experiments that show how surface finish affects emissivity and absorptivity, and the area factor for heat transfer. The light source uses a low voltage lamp inside an integrating sphere to create a diffuse light. Students can rotate the light source through a range of angles (shown on a protractor scale) for experiments in light direction. A moveable Lux Meter measures the light radiation from the light source at varying distances.
TecQuipment includes different optical filters (coloured, neutral density and infrared block). They allow extra experiments that show how optical filters affect light transfer.
A clear, multiline digital display on the Control Box shows temperatures and light or heat radiation.
You can do tests with or without a computer connected. However, for quicker tests with easier recording of results, TecQuipment can supply the optional Versatile Data Acquisition System (VDAS). This gives accurate real-time data capture, monitoring and display, calculation and charting of all the important readings on a computer (computer not included).
