Electric Field Meter

Function and Applications

The electric field meter is a compact and highly sensitive instrument for measuring the field strength of electrostatic fields as well as high-impedance voltages. Measurement is based on the field mill / induction principle. Operation is carried out via a USB interface in combination with a computer and the corresponding measurement software.
