Specification:Material: GlassColor: YellowSize:14cm*7.5cmPackage Included:1 x Crookes RadiometerRemarks: The black coating on the blades of the windmill is easy to fall off. So far, there is no good way to solve it. Especially in the express delivery and vibration process, we can see that the blade is painted off, or there is black powder in the ball, Please also understand.

  • ♥[Science laboratory equipment]: This radiometer can display the heat radiation emitted by the light source. When you put the radiometer in the sun, the blades will continue to rotate. It can also be used as a simple test instrument for you to test the light source, easily helping you complete the intensity comparison of the light source.
  • ♥[Including classroom science supplies]: Each set includes a radiometer, about 5.11 inches high. It is very beautiful to put it in the office or living room.
  • ♥[Easy to use radius meter]: The dark light and light fan in a glass sphere with a diameter of 7.5 cm can absorb light at different speeds, and the blades rotate, depending on the intensity of the light.
  • ♥[Ideal tool for science classes]: Very suitable for education, research, solar energy and all types of science. This is a creative gift that we can give to our friends or family. They will love it!
  • ♥[Science Class Set]: For any children's solar experiments, this radiometer is very suitable for classroom use. Made of glass, fragile. Suitable for children over 14 years old.
