A first-rate apparatus for demonstrating static electricity
Generates potentials as high as 400,000 volts Produces sparks as long as 15 in
(38cm) Belt current charges the dome at 10μA; replacement belts are available Operates on 110VAC with grounded cord Rotary Dial located in the unit's base allows you to vary the motor's speed Terminal located on the 9.8 × 11.8 in
(25 × 30cm) base is grounded to safely produce sparks and discharge the dome Aluminum Sphere is 9.8 in
(25cm) diameter; creates sparks of great intensity Aluminum electrode (sold separately) is supported by an insulated, polycarbonate column Overall height: 29.9 in
