Capacitance Thickness Gauge / Displacement Gauge Frequently Asked Questions

Conductors
material and surface condition do not matter. Items with a line resistance of less than several kΩ/cm can be measured as they are. Additionally, even insulators that are covered with a conductive surface can have their total thickness measured.

Semiconductors
Silicon-based wafers are not a problem, but gallium arsenide and sapphire-based ones have items that can be measured and those that cannot be measured depending on resistivity. Please consult us.

Insulators
such as glass, polyethylene, and polypropylene plastics. (Thin objects composed of a single material with uniform properties are the subject of measurement.)
