Features
Experimental unit for investigating thermal and visible radiation
Wide range of experiments1
User-friendly software with options for saving, printing and creating diagrams

Tesca Thermal Radiation Apparatus 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 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. At the same time, the measured values can also be transmitted, optionally directly to a PC via USB. The data acquisition software is included.
