Electrostatic field strength meter

IThis is a small, handy field strength meter with digital display used to measure electrostatic fields. By selecting the measuring distance, the field value in volts is obtained directly.

The housing is made of antistatic plastic with laminated front side. The influence measuring electrode is star-shaped. A grounded modulation rotor with the same star shape rotates at a short distance from the electrode. An annular electrode system surrounding the influence electrode serves as mechanical protection.
