Description Tellurium TL 08 - hand-operated A model of the sun on a stable metal base. The top of the sun is detachable for easy replacement of the filament lamp. Compared with the hand-operated TL 05, the bracket for the earth-moon system has been shortened with these advantages: - greatly improved shadowing effects (even without darkening the room) - unit comes completely assembled (all you need to do is put on the earth and slip on the moon)
Easy operation Once you have put on the terrestrial globe, slipped on the moon rod and plugged in the electric cable, the Tellurium is ready for use. The earth-moon system sits on a bracket which has an extension in the shape of a handle. The movement of the earth around the sun takes place at this grasp. A pole rod may be pulled out to illustrate the change in direction. The position of the moon can be changed by hand for demonstration purposes.
Impressive demonstration The unit provides easy-to-understand answers to elementary questions, even in primary education, such as: - Why do day and night alternate? - How are summer and winter distributed on earth? - Which constellation outshines the sun? - What are lunar and solar eclipses about? - What exactly is a month? - In which position is the moon invisible/partly visible/fully visible from earth?
TL 08 SPECIFICATIONS Diameter: 26 cm Height: 33 cm Weight, approx.: 4 kg Dia. Sun: 20 cm Earth: 12 cm Moon: 3.5 cm Distance sun to earth: 50 cm Power supply: 230 V AC Light source : E 14 40 W frosted
Accessories incl. optional. –earth, complete - arrow, compl., artno.020.3 –moon with rod (to demonstrate direction of sunrays) –electric cable

Tellurium TL 05 - hand-operated
A model of the Sun on a stable metal-base plate beams light onto the Earth and Moon to produce impressive shadowing effects. The Earth and Moon models are mounted on a bracket which extends beyond the Sun in the form of a handle. This is used to operate automatic the entire system by hand at a speed suitable for the demonstration and makes it possible to repeat characteristic motions as required.
TECHNICAL DATA:
Diameter: 260 mm Height: 330 mm Weight, approx. 5 kg Diameter- Sun 200 mm - Earth 120 mm - Moon 35 mm Distance from Sun to Earth 800 mm Power supply 230 V AC Light source E 14 40 W frosted Packing 580 x 400 x 420 mm

Tellurium TL 06 - electrically driven -
The Earth - Moon system is moved by an electric drive. The annual revolution of the Earth - Moon system around the Sun can be demonstrated manually. An extremely low speed can be chosen to demonstrate the related motions. Advantage: The bracket remains stationary, motions can be repeated as required. A different light source (projection system) demonstrates all shadowing effects even more clearly.
TECHNICAL DATA
Diameter: 260 mm Height: 330 mm Weight, approx. 6 kg Diameter- Sun 200 mm - Earth 120 mm - Moon 35 mm Distance from Sun to Earth 800 mm Power supply 6 V stabilized Light source 6 V / 500 mA Packing 580 x 400 x 420 mm
