| Product Information: .. |
Its main component is the electric field mill: a modulating chopper wheel of the same star shape, connected to ground, is mounted at a small distance in front of a star-shaped measuring electrode. The electric field causes electrostatic induction of charges, which generate an alternating current proportional to the field strength. This alternating current is converted via a synchronous rectifier and a low-pass filter into a bipolar DC voltage, without energy being extracted from the electric field in the time average.
The apparatus has overvoltage protection. A standard DC voltmeter can be used to display the measured values. The built-in FireWire socket enables connection of the data logger / interfaces VinciLab 2 (item no.: 1021477) or WiLab (item no.: 1022284).
