The EM03 Electric Field Meter is a small, compact unit with digital display for measuring static charges directly in Volts. The mode of function of the instrument is based on the influence principle. When measuring static charges, the distance between the instrument and the object is selectable between 1 and 20 cm. The integrated micro-computer automatically converts the measured fieldstrength over the pre-selected measuring distance (distance between measured object and measuring electrode) into charges in Volts.

The electric field meter is a parametric amplifier. The charges influenced by the electrical field generate an alternating current proportional to the field strength. This alternating current is measured via a selective amplifier without drawing time-averaged energy from the electrical field. No radioactive substances are used in the instrument. The instrument is encased in an antistatic plastic housing with membrane front plate. The star-shaped influence measuring electrode is built into an aluminium front plate. A modulation wind mill-type wheel of the same star shape, connected to frame, rotates...
