Testing Function
Measuring the sheet resistance (R□) and volume resistivity of thin films and surface functional coatings at elevated temperatures up to 1600°C is critical for aerospace thermal barrier coatings, transparent conductive oxides (ITO), and high-temperature interconnects. Utilizing the dual-configuration four-probe technique, this system eliminates the need for geometric correction factors, delivering pure sheet resistance and conductive transition curves.
