【Volume and surface resistivity of PCBs and polymer materials】
Evaluates insulation and antistatic performance. Voltage is applied through the sample surface for surface resistance, or through the thickness direction for volume resistance.
【Volume resistivity of insulating sleeves and tubes】
Supports special-geometry samples such as sleeves and tubes that cannot be configured with the standard double-ring electrode method.
【Resistance measurement of conductive packaging materials】
Conventional packaging materials can accumulate and discharge static electricity, potentially damaging electrostatic discharge sensitive (ESDS) devices. Material characterization is performed to evaluate packaging designed to prevent such damage.
【Insulation resistance measurement】
Covers interlayer insulation resistance of copper-clad laminates, pattern-to-pattern insulation resistance of PCBs, and two-point insulation resistance of electronic components and finished products.

Current flowing through a sample under applied voltage is measured, and volume or surface resistivity is calculated based on sample dimensions and electrode configuration. Insulation resistance values up to 1.0×10¹⁷ Ω are measurable. Evaluation under various temperature and humidity conditions is supported through combination with a temperature/humidity chamber.
