Handy, mobile electric field meter with digital display for measuring electric fields and electrostatic charges. The measured field strength (V/m) is automatically converted into the voltage potential (V) over the set measuring distance. Measured field strength (V/m) is automatically converted into surface potential (V) over the set measuring distance in ´Distance´´ mode - The actual field strength (V/m) is displayed in the additional ´´Field Strength´´ mode - Version:without case - 1 piece EFM 51 electric field meter - 1 piece storage bag (860840 only) - 1 piece conductive carrying case (804671 only) - 1 piece earthing cable - 1 piece factory calibration certificate - 1 piece operating instructions (German/English) - 1 piece 9 V battery´
