Measurement Range

ONLY Napson manufactures both Contact and Non-contact resistivity measurement systems.
Please refer to the tables below for features & resistivity ranges of each measurement type.
For additional information, please contact us by the Contact form.

Contact type
[4 point probe method]
Non-contact type
[Eddy-current method]
Measurement area 3mm(or 1.5~4.77mm) Φ5~60mm
Probe Gap
(*Determined by test sample thickness)
Contact 0.1~10mm
  • Measurement is absolute
  • Narrow measurement area
  • No damage by contact
  • No influence of contact resistance
  • Sample may be damaged by probe contact
  • Calibration to a reference resistivity sample is required
  • Sample thickness is limited by probe gap
