High quality apparatus for professionals
DC Four Point Probe systems is one of the most reliable methods for resistivity
or sheet resistance measuring of conducting materials.
It is well known among probing engineers
that the quality of the probing apparatus
greatly affects the probing accuracy.
Especially for the probing of semiconductor materials, not only the accuracy
but also the durability is crucial.
Our Four Point Probe manufactured by skilled
worker is universally acknowledged as a high
