A portable cup anemometer, which gives direct readings of wind speed in either km/hr, Beaufort scale, m/s or knots. The vertical spindle carries three plastic cups, which rotate on ball bearing and giving reading through meter. Supplied with Instruction Manual.

For simultaneous registration of temperature, relative humidity and barometric pressure and wind direction. Consists of a metal enclosure with dial type hygrometer, barometer and thermometer mounted inside.

For simultaneous registration of temperature, relative humidity and barometric pressure and wind direction. Consists of a metal enclosure with dry & wet bulb hygrometer, barometer and thermometer mounted inside. The wind wane is mounted at the top of enclosure.

A circular 10cm dial is graduated. Also marked in inches and mm of mercury. With rubber compression bulb and tubing connection for varying the air pressure arbitrarily to show the effect of increasing or decreasing pressure. Graduated from 960 to1060mbar ´ 1mbar.

For demonstration of respective positions and the motions of the Earth, Moon, and Venus around the sun. Rotation of the handle makes the earth to move around the sun, while revolving on its own axis, the moon moves in its orbit around the earth, and venus will follows its path around the sun. It also demonstrates the causes of the seasons, day and night, phases of the moon, and many other related phenomena. The large sphere is the sun, with Venus near it, and at the end of 16½ inch arm is the Earth with the moon near it. A 220V lamp inside the sun globe projects a beam of light directly on the earth for a clearer visualization of the change of seasons on the earth and to illustrate eclipses.

An instructive demonstration model of the solar system. Illustrates the complete solar system, the relative sizes approximately and colors of the planets, the position of each of the 9 planets with respect to the sun as center of their rotation. Along with each planet, their important moons are also shown. A 220V lamp inside the sun globe projects a beam of light on the planets. The planets are arranged to move around the sun in same sequence as that of original solar system. Their situation in 12 zodiacal signs can be shown from the printed base. Complete with instructions.

For demonstration purpose. The unit consists of a sensitive solar cell mounted on a box with 4mm sockets and ON/OFF switch. A mini-motor is mounted inside the box with its shaft protruding out on one side of the box. A plastic fan is mounted on the shaft. When switched ON with sufficient sunlight falling on solar cell, the motor rotates which can be observed from the rotation of the fan, showing conversion of solar energy into electrical and then into mechanical energy.

Demonstrates the working of water turbine for generation of electric power as in hydro-power stations. When water is made to fall on the vanes of turbine from inlet at the top, it makes the vanes of the turbine to rotate and escapes from the outlet at the bottom. A dynamo coupled to the shaft of the turbine rotates with it resulting in conversion of mechanical energy of rotation into electrical energy, which can be observed from the glow of indicator lamp. Both the inlet and outlet have serrated tubulatures for flexible tubing connections. Mounted on base.
