Handheld Four Point Probe / Portable Four Point Probe /​ Handheld four-point probe holder

• 4 point probe head with spring loaded probe tips coated with Au

• 4 point probe head connected with full coaxial cables connected isolating charges from operation for high noise immunity of signal.

• The exposed probe length can be adjusted and fixed in response to the probe being applied to the sample pressure

• Increase the contact area between the probe base and the sample, so that the operator does not shake due to the hand pressure, which causes measurement error and improves measurement stability.

• From the probe tip, the hand grip, the signal line to the input end of the instrument, the anti-noise processing is performed, so that the operator does not have static electricity due to the static pressure, which causes measurement error and improves measurement accuracy.

• Can measure high hardness such as twins and other conductive materials
