| CROOKES RADIOMETER - DOUBLE VANE | Comprises A partially evacuated glass bulb containing one set of four mica vanes mounted on A pivot. One side of each vane is blackened, the reverse side shiny. The presence of heat or light energy causes the vane to rotate. This double vane type has contra-rotating vanes.NOTE: This radiometer is designed for demonstration purposes using A heat or light source to provide the energy to rotate the vanes and will not necessarily work when exposed to sunlight. If the sun is too high in the azimuth its rays will not strike the vane at the correct angle to provide sufficient energy for them to rotate. Code: HE0096.
