3. The four-probe method for powder testing is in accordance with the requirements for the four-probe method in the arbitration method, as specified in the GBT 30835-2014 "Lithium-ion Battery Carbon-Composite Phosphate Iron Lithium Cathode Material" regarding the determination method of powder electrical conductivity.

ThreeApplication Scope:

Measurement of the resistivity for the lithium-ion battery cathode material, lithium iron phosphate, in carbon composite form.

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

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

4. Film Resistor Measurement

5Used for corporate quality inspection; R&D departments, colleges and universities; research institutions; and quality testing agencies.

FourPrinciple of Operation:

During the compression process by external forces, as the powder moves and deforms, the voids are filled, the contact area between particles increases, causing an attraction between atoms 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 forming of the blank until it stabilizes.
