Product Overview:

The powder resistivity tester is mainly used as a specialized instrument for measuring the resistivity of powder materials

Due to the different densities of powder materials, the data obtained from testing under loose and compacted density conditions are different. Therefore, testing powder electricity

Resistance requires testing to be conducted under specified pressure conditions Facilitating effective data testing and comparison

The instrument consists of two main parts: the host and the testing rack. The host includes a highly sensitive DC digital voltmeter and a highly stable DC constant current source for measurement

The experimental setup is operated and set through a touch screen, with a reasonable page layout and user-friendly design, and the test results can be printed.

The instrument has the characteristics of high measurement accuracy, good stability, compact structure, and easy use, which meet the requirements of international and national standards.

The instrument is suitable for industries such as conductor powder, semiconductor powder, and carbon materials for testing and inspection.
