Electrostatic field meter with carry case, 0 to 200 kV, 1 to 20 cm distance - A1-ESD EP0201012

The EFM 822 electrostatic field meter measures static charges without contact and automatically converts the measured field strength (V/m) into voltage potential (V) using the selected measuring distance. The antistatic, EPA-compatible plastic housing and single-button operation make it straightforward in daily use.

The carry-case kit (ZBS) supplies the meter ready to use in an ESD case with conductive foam insert, so you can check ESD workstations and ionisers without buying further parts.

Key benefits

• Menu-driven distance pre-selection with five distances, removing manual potential conversion
• Hold function freezes the reading for accurate measurement in hard to reach places
• Very high zero-point stability, no zero adjustment required before each measurement
