The Four Probe Setup (FP-01) is a precision instrument used to measure the resistivity and energy band gap of semiconductors such as germanium and silicon. It employs the four-probe method, which eliminates contact resistance and provides accurate measurements of bulk resistivity and temperature dependence. The setup includes a high-impedance digital voltmeter, constant current source, and a built-in oven with a digital temperature controller. It is widely used in physics and electronics laboratories for materials characterization and semiconductor research. Key Features:
