List 5 product

Jandel Very Close Spacing Probe

This probe uses a staggered jewel arrangement in order to acheive probe spacing of 0.500mm spacing.
The picture to the left compres a ‘standard’ 1.591mm spacing probe with the 0.500mm spacing probe
This probe can be used for probing close to sample edges or where a sample has very small dimensions.

Jandel Hall Effect Four Point Probe

Low Profile Probe for Hall Measurements

Jandel Engineering Limited manufactures this low profile probe head for
use in making four point probe measurements associated with Hall
measurements.
All Jandel probes are built to a high level of mechanical accuracy.
Specifications for radii, spacing and planarity are verified by video inspection
system and optical interferometer. Loads are verified by electronic force gauge.
Each probe has upper and lower jeweled needle guides.
It should be noted that while this probe was manufactured for placing
between the poles of a magnet Jandel Engineering does not supply any other
equipment or accessories for such measurements.

Jandel Macor Four Point Probe

The Jandel Macor Probe head is suitable for use in a wide range of temperatures – approximately -190C to 300C (around 80K to 600K).
The high temperature is given for measurement in an oven. It is possible to measure samples are higher temperature where the sample is heated using a hotplate and the contact time with the sample is not excessive.

Jandel Custom Probes

We have produced various probes to customer specifications including three, four, five and six point probes.
If you require something out of the ordinary we would be pleased to discuss what options might be available as a solution.

Jandel High Vacuum Four Point Probe

Cylindrical Probe For Use At High Vacuum

Jandel Engineering Limited manufactures a version of the cylindrical probe
which can be used at high vacuum.
The probe is unanodised and has had blind holes removed where possible.
High vacuum wire is used for the connections which are crimped rather than
soldered. A ruby ball is used for the insulation pad.
All Jandel probes are built to a high level of mechanical accuracy.
Specifications for radii, spacing and planarity are verified by video inspection
system and optical interferometer. Loads are verified by electronic force gauge.
Each probe has upper and lower jeweled needle guides.
