Manual four point probes

Jandel manufactures a broad range of manual test equipment.
Constant current source and digital voltmeter available combined in one case.


Multiposition Wafer Probe

8" and 6" versions available.
Lever operated probe with switched current leads to prevent sparking.
Repositioning accuracy within 1mm
Precision low maintenance slides
Shrouded measuring area to minimize light and electrical interference.


Multiheight Probe

Height adjustable to cope with samples from thin layers to ingots.
Lever operated probe with switched current leads to prevent sparking.
Measures samples up to 10" deep.
Width of sample limited only by need to support ends.


Hand Applied Probe

Insulating PTFE body.
4-point cylindrical probe head is easily changed.
Shorting switch to prevent sparking.
Easy placement by hand.
Measurement of large samples unable to fit on standard test equipment.


Universal Probe

Highly repeatable needle contact conditions.
Individually adjustable needle loadings with direct indication of set load.
Micrometer controlled slice displacement.
4-point measurement of wafer resistivity and 3-point spreading resistance measurements.
Hinged steel cover to eliminate effects of light and electrical interference.


Microposition probe

X-Y Micro-manipulation of small samples.
3" diameter sample capacity.
Sample can be retained by vacuum.
Lever operated probe with switched current leads to prevent sparking.


RM3 Test Unit

The new RM3 has a smaller footprint, a wider current range, a wider voltage range, and will have RS232 and USB connectivity. (As compared to the RM2).

Readings can be displayed as voltage or alternatively direct readings in Ohms/square will be available.


HM20 Portable four point probe test meter

Portable meter designed for use with a four point probe to make resistivity measurements.
The HM20 supplies a constant current and displays either the resultant voltage or the sheet resistance in ohms/square depending which function has been chosen.

The HM20 can be combined with the Hand Applied Probe to make a complete portable four point probing system.
