MCE 34 is a device used to measure electrostatic fields. It has an analog display, three measuring gauges and a large field mill for precise measurements.
The housing of this instrument is made of aluminum, making it light and sturdy. The influence measuring electrode is star-shaped. A grounded modulation rotor with the same star shape rotates at a short distance from the electrode. A system of annular electrodes surrounding the influence electrode serves as mechanical protection.
