Thermal Radiation Unit

The Thermal radiation is detected by a thermopile, and the optical radiation is recorded by a photometer. Various optical elements are mounted on the optical bench between the emitter and the detector, and the distance between each optical element can be read from the ruler along the optical platform. The Radiant Energy Transfer test bench is a training and teaching device used by the laboratory to verify the changes in radiant energy transfer. The experimental bench contains two radiation sources: a radiator and a light emitter (radiation power can be adjusted). You can rotate the illuminance meter to study how the angle of incidence affects the radiation intensity. The matching optical components are used to study the reflection, absorption and transmission of different materials at different wavelengths and temperatures. The measured value is directly displayed on the measuring amplifier in digital form, or it can be directly transmitted to the PC section through USB for further processing. Experiments can verify Kirchhoff’s radiation law, Stefan-Boltzmann’s law, Lambert distance and direction law and other basic heat transfer laws. 

Features:

The experimental table is equipped with blackboard, whiteboard and filter to simulate different radiation surfaces such as black body, white body and transparent body;

Transient data during the change of the workbench is directly displayed on the measuring amplifier in digital form;

The data of various physical quantities in the changing process of the workbench can also be transmitted to the PC through the USB interface for further processing;

Radiant energy transfer experimental platform can accurately measure the radiant heat flux density and verify the basic laws of surface radiant heat transfer;

The power angle of the radiation source of the experimental platform can be continuously and smoothly adjusted.
