Please note, this probe head is not suitable for silicon or other materials which naturally form insulating oxide layers. To measure such materials, the oxide layer needs to be penetrated by the probes, which may not be possible with the spring-loaded, round tipped probes utilised by this probe head.

Probe Radius 0.24 mm
Probe Stroke 1.4 mm
Spring Force 25 - 60 grams
Maximum Current 2 A
