A rugged unit that will develop potentials up to 75,000 volts on the polished, anodized dome. Provides the power to execute all the basic electrostatic demonstrations on an energetic and dramatic scale. The maximum continuous current is only about 10 microamperes, so the unit is quite safe. The standard machine has a negative dome. This will create a fantastic display of static electricity for your next science lesson!
