This dual purpose electroscope has a metal plate to which a single gold leaf may be attached and is supported by an insulating bush in a metal case with 4mm socket earthing terminal. A scale is provided for measuring the deflection of the leaf.
Packs of gold leaf available on order code 52-2661.
Q. what's the second purpose? :) - I'm buying one for sense an electrostatic field, looking forward to the bonus ...
A. Hi Ray, thank you for your question. The 'dual' reference appears to refer to the inclusion of the scale. Not only does it detect or sense an electrostatic voltage (purpose #1), you can also read the deflection on the scale enabling, for instance, comparison of two voltages from different sources (purpose #2).
