4 Point Probe Heads

---

Cartridge type, Cylindrical type, Miniature - Probe Head Only

​​DESCRIPTION: Napson 4-point resistivity / sheet resistance systems use high performance probe heads made by Jandel Engineering Limited of England.

• Jandel probe heads perform highly precise measurements of resistivity and sheet resistance for silicon wafers, epitaxial layers, diffusion layers, ITO layers, metal layers and more.  Jandel probes have been an industry standard for many years.
• Load (needle pressure) is very stable with a "V" type spring
• Probe spacing accuracy and probe stability are excellent with jeweled upper and lower guides.
• Durable probe needle tips – Solid tungsten carbide for superior durability

APPLICATIONS: The probe type is chosen under the material of measuring sample, the surface state, the form etc.
