Four-probe sheet resistance & electrical conductivity meter

Ossila 4prob
The most common technique used for measuring sheet resistance is the four-probe method. This technique involves using four equally-spaced, co-linear probes (known as a four-point probe) to make electrical contact with the material.
Applications: Material characterization, Thin-film Solar Cells and LEDs

DC power supply (Manson, 0.1 – 30V)
