Electrostatic Fieldmeters

Electrostatic Fieldmeters 

measure the electrostatic field strength (voltage per unit distance) between the probe and the material under test. Probe-to-surface separation must be carefully controlled for accurate measurement, allowing field strengths in the hundreds of kilovolts can to be measured. Monroe fieldmeters use a feedback-driven design to assure accurate, drift-free, non-contacting measurements.
