Surface Resistance Meter Semizond 4K for Accurate Electrical Measurements

The meter is a functionally and structurally complete product designed to measure by the four-probe method (Kelvin method) the specific surface electrical resistance of plates of semiconductor and dielectric materials with a linear arrangement of probes.
The Meter is a product designed to measure the surface resistivity of dielectric or metallic samples with a linear arrangement of probes using the four-probe method (Kelvin method).
The Meter measures the potential difference between two probes of a four-probe measuring head mounted on the surface of a material sample when an electric current of a certain magnitude and alternating polarity is passed through two other point probes located on the same surface.
