ThreeApplication Range:

Measurement of the resistivity for the lithium-ion battery cathode material, lithium iron phosphate (LiFePO4), with carbon composite.

2. Analysis and testing of semiconductor powder materials requiring the four-probe method for measurement.

3. For measuring the resistivity of powdered materials like graphite.

4. Thin Film Resistance Measurement

5For corporate quality inspection; R&D departments, colleges and universities; research institutions; and quality testing organizations.

FourPrinciple of Operation:

During the compressive process by external forces, as the powder moves and deforms, the voids are filled, the contact area between particles increases, causing interatomic attractions and strengthening the mechanical wedging between particles, thereby forming a compact with density and strength.Real-time measurement of resistance, resistivity, and conductivity changes during the blanking process until stabilization.
