The intensity of thermal and visible radiation can be adjusted. Colour filters and apertures extend the range of experiments. The measured values are displayed digitally on the measuring unit. The experimental unit contains a blackbody emitter with a thermopile for the investigation of thermal radiation, a light source with luxmeter for illuminance measurements, and absorption plates with thermocouples for the investigation of Kirchhoff's laws. The data acquisition software is included. At the same time, the measured values can also be transmitted directly to a PC via USB.
