Electrostatic field meter with analogue output and case, 0 to 200 kV - A1-ESD EP0201013

The EFM 823 electrostatic field meter measures static charges without contact and offers all EFM 822 functions. It additionally has a ±1 V analogue output that is enabled in the manual field-meter ranges and allows readings to be recorded.

Supplied in a practical case kit (ZBS), the meter is ready to use for checking electrostatic charges at ESD workstations.

Key benefits

• ±1 V analogue output proportional to field strength for external recording
• Menu-driven distance pre-selection with five distances, no manual conversion
