Product Overview:

Semiconductor material resistivity tester-It is mainly used to measure the resistivity of intermediate samples of rubber and plastic semiconducting materials for cables, as well as the resistance of various conductive rubber products. It can also be used with a four terminal test clamp to measure the low and median resistance of metal conductor materials and products.

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. The measurement results are directly displayed using LED digital display, divided into three windows: voltage display window, material thickness display window (user input based on actual measurement), and resistivity display window.

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 cable factories, conductive rubber material factories, computer factories, electronic watch factories, universities, scientific research and other departments. It is a necessary testing equipment for resistance performance testing and process testing of conductive rubber materials and products.
