a

1 FAN Desk fan, for providing a convenient source of air-flow for wind- energy investigations. Also useful for keeping cool in hot weather! 30cm diameter. 230 Volts a.c. Cat No. Description Price Per FAN-100-100 Fan 19.57 ea. 2 MINI WIND TURBINE This mini-turbine can be used to introduce basic principles of a wind turbine. It consists of a small electric motor attached to a propeller and connected to a pair of terminal posts. To demonstrate how the turbine can generate an electrical current, it can be connected to an LED or electric motor. To measure the output, it can be connected to a voltmeter or digital multimeter – the faster the turbine turns, the higher the voltage reading. The mini-turbine can be used to carry out simple investigations into the effects of different wind speeds and angles on output, using a desk fan, for example. The wind speed can be varied by using the settings on the fan. The mini-turbine can be held in the hand or, for a more quantitative approach, held in a clamp stand, which allows distances and angles to be measured more accurately. Cat No. Description Price Per EWE-730-100 Mini Wind Turbine 14.34 ea. 3 WIND TURBINE KIT To measure the power of wind. Contains all that is needed to convert wind energy into electricity. By increasing the number or angle of turbine blades, effects can be measured. The kit can be used indoors using a desk fan. Cat No. Description Price Per EWE-750-100 Wind Turbine Kit 165.75 ea. 4 WEATHER VANE BY ‘INVICTA’ A simple, practical weather vane which can be handheld or permanently fixed. It can be completely dismantled which encourages children to incorporate any part into their designs. Cat No. Description Price Per EWE-700-100 Weather Vane by ‘Invicta’ 11.04 ea. 5 ANEMOMETER, INVICTA A unique design feature gives a direct reading of wind speed without the need to count revolutions. The low & high calibrations register ms-1 and the Beaufort scale. Can be handheld or fixed permanently. Cat No. Description Price Per EWE-300-100 Anemometer, ‘Invicta’ 19.05 ea. 6 ANEMOMETER MINI This easy-to-use mini vane thermo anemometer has user selectable measuring units for air velocity and temperature. The lightweight, slim line unit also displays minimum and maximum measured values since power on. • 0.4 to 30m/sec x 0.1m/sec • Selectable measurement units: m/sec ft/min, mph, km/hr or knots • Temperature -30° to 60°C • Sapphire jewel bearing ensures fast and accurate readings • 30mm LCD display with function indicators • Sampling rate of 1 reading per second • LCD Backlight for applications in low light environments • Min Max Memory since power on • 4mm Camera Bush • Auto Power Off after 15 minutes of no activity • Low Battery indication • 2 Year Warranty • Supplied with battery Cat No. Description Price Per EWE-355-100 Mini Amemometer 37.72 ea.
