LSFM-100 four point measurement system

The LSFM-100 four point measuring system is to arrange the probes on the object to be measured in sequence and at equal intervals, apply appropriate pressure, and the probes form ohmic contact with the object to be measured. The resistance and square resistance of the object to be measured can be measured, and the resistivity of the object to be measured can be calculated when the thickness of the object to be measured is known. The independently developed control software matched with this syst
