Axazcs Solar Altitude Angle Measurement Instrument, Measure Solar Altitude Angle, Real-time Azimuth Angle, and Solar Projection Length, with Compass & Angle Plate, for Science Educational
£34.23
Product Description
✔ The four seasons of the earth and the alternation of day and night are closely related to the sun. During the 365 days of the year, at the same time and place, the sun's position is also different ✔ The sundial invented by the ancients based on this law is a tool that uses the projection of the sun to indicate time. It is used to reflect the four seasons, temperature, phenology and other conditions, and to calculate the twenty-four solar terms of the year ✔ This instrument also uses the principle of solar projection: it can measure the height angle and real-time azimuth angle of the sun, and it can also measure the length of the sun's projection ✔ The angle plate is a semicircle with a radius of 60mm, which is assembled in the center of the chassis through the angle plate bracket. The geometric centerline of the semicircle is calibrated as "0°" and has scales of 0-90° on both sides ✔ The compass is fixed on the 0° scale line. The projector composed of the projection hole and the screen is fixed above the angle plate
