Monroe Electronics originated the feedback electrostatic  voltmeter in the 1950's. We have committed ourselves to producing the highest quality instruments ever since. Today's Monroe Electronics electrostatic  voltmeters provide non-contacting measurement of electrostatic surface potential  on insulating, conducting or semiconducting materials. They are distinguished by  their reliability, high accuracy typically 0.1% or better almost regardless of probe-to-surface spacing, and by their ability to resolve targets as small as  0.1" (2.5 mm) diameter or smaller. Monroe Electronics voltmeters function by means of a high voltage amplifier that automatically drives the probe to the same potential as that of the surface under measurement. By simply metering the  output of the high voltage amplifier, one has an accurate indication of the unknown potential. This null-seeking operation, using patented feedback  circuitry, makes the instrument remarkably stable, virtually drift free and  highly accurate.  Your voltmeter choices are outlined above:

If you need  to see voltages on PCBs, use a fieldmeter. If you need to see voltages on individual circuits, or leads on a DIP, voltmeters are your choice.
