電阻計
Specialty resistance and resistivity metersare
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.
