Entry-Level Manual Four-Point Probe Measurement System (190 × 190 mm)

AiT CMT-100S is an entry-level manual four-point probe measurement system distributed by Zhidian. It uses a Signatone probe to accurately measure surface resistance (ohm/sq) and volume resistivity (ohm·cm). The integrated controller and measurement stage save space, while the internal modular slot design simplifies maintenance. This standard four-point probe system offers high accuracy, stability, and excellent value.

・Surface resistance measurement for industries such as wafers, thin films, and solar energy
・Surface resistance measurement units: ohm, ohm/sq, ohm·cm & S
・Easy operation (manually lower the lever to measure a single point at the center)


CMT-100S Four-Point Probe System Specifications

The CMT-100S is an entry-level manual four-point probe system for measuring surface resistance and volume resistivity. It uses a Signatone probe and an integrated controller and measurement stage. Check sample dimensions, surface condition, probe contact, and test objectives when selecting a configuration.

SpecificationCMT-100S
Measurement range1 mΩ/sq–2 MΩ/sq
Operating methodManually lower the lever to contact a single point at the center of the sample, then take the reading. This is a manual single-point system.
