Monroe feedback electrostatic voltmeters originated in the 1950s. Electrostatic voltmeters measure surface potential on various materials without contacting the measured surface. They are distinguished for their high accuracy, typically better than 0.1% of full scale, and provide stable, drift-free, low-noise measurements that are independent of probe-to-surface separation.
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.
Charge Plate Monitors 靜電消除檢測儀
Charge-plate monitors evaluate the quality of air ionization systems used to neutralize static charge accumulation. Charge-plate monitors measure both positive and negative discharge times to evaluate the production of the air ions used to neutralize charges, plus ion balance voltage.
Specialty resistance and resistivity meters are used to evaluate static dissipative materials, packaging, flooring, work surfaces, garments, and other items that are used in ESD static control programs.
Models are available to measure surface resistivity, surface resistance, volume resistivity, volume resistance, point-to-point resistance, and point-to-ground resistance.
