Product Overview:
The powder resistivity tester is a special instrument mainly used to measure the resistivity of powder materials.
Due to different compactness of powder materials, the data obtained under loose and tapped density conditions are different, so testing powder electrical
resistance requires testing under specified pressure conditions to facilitate effective data testing and comparison.
The instrument consists of two main parts: the main unit and the test stand. The main unit includes a highly sensitive DC digital voltmeter and a highly stable DC constant current source.
The test settings are operated and set through a touch screen, with a reasonable page layout and user-friendly design, and test results can be printed.
The instrument features high measurement accuracy, good stability, compact structure, and ease of use, fully meeting international and national standards.
The instrument is suitable for industries such as conductive powders, semiconductor powders, and carbon materials, and is an essential testing device.
