Abstract
An electrostatic voltmeter for measuring the surface potential of a charged body, includes a detecting electrode locatable adjacent to the charged body, and a vibrating element having a pair of parallel spaced legs between which the detecting electrode is disposed in spaced relation. The vibrating element is vibratable such that the legs move toward and away from the charged body. The vibrating element may extend transversely or parallel to a line connecting the charged body and the detecting electrode.
