ZT0007 Thermal Radiation Unit Teaching Equipment Heat Transfer Experiment Equipment

1 Product overview

1.1 Overview

The ZT 0007 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). 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. 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. Experiments can verify Kirchhoff’s radiation law, Stefan-Boltzmann’s law, Lambert distance and direction law and other basic heat transfer laws. 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. Students can familiarize themselves with the basic knowledge of thermal radiation through related experiments, and cultivate the corresponding knowledge and skills of students and the ability to innovate and develop. .
