WL 362 Thermal Radiation Unit Show data sheet (pdf file) Print page
Technical Description

  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 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 directly to a PC via USB. The data acquisition software is included.
