Jandel Four-Point Probe Heads

Jandel manufactures the highest quality four-point probe heads available anywhere in the world and has models for all known types of four-point probing systems. These premium quality, jewel bearing four-point probe heads have been sold to the OEM equipment market since 1967 and are standard equipment on most brands of auto-stepping resistivity measurement equipment. Bridge Technology offers the Jandel line of four-point probes directly from Jandel to end users at significant savings when compared to the prices that OEM's typically charge.

Features include:

• Upper and lower jeweled needle guides
• Solid tungsten carbide needles for superior durability (osmium alloy available)
• Video inspection system and interferometer used to verify accuracy of tip radii, spacing and planarity
• Tip spring loads are checked by electronic force gauge for specific tolerances of accuracy (for complete description of probe accuracy, click this link)
• Three basic shapes will fit all mountings and systems
• Anodized aluminum alloy construction with internal Teflon insulation for low leakage
• Most models are available in linear, square, or rectangle array (Compact, Miniature, and Macor models are only available with linear array). Square and rectangle array probes can have tip spacings from 0.635mm up to 1.591mm, but not the close spacing of 0.5mm. The probe array does not affect the price of the probe.

Misc

• Jandel offers a variety of specialty probes including probes for hi-vac use, cryogenic use, high temperature, 5-point probes, close spacing probes, Hall measurement probes, etc.
• A chart is available that shows some typical probe tip spacings and tip radii

4 Point Probe Head Specifications

What goes into making a Jandel four point probe head?

The work involved in building a Jandel four point probe head is similar in some ways to horology (watchmaking) in that it is laborious, meticulous, and time consuming. The managing director of Jandel is, in fact, a trained horologist.
