GEST-111 semiconductor resistivity tester Introduction: The semi-conductive rubber and plastic resistance tester is mainly used to measure the resistivity of the intermediate samples of rubber and plastic semi-conductive materials for cables and the resistance of various conductive rubber and plastic products. The four-terminal test clip can also be used to measure the low and The median resistance is measured. The instrument is composed of a host and a test frame. The host includes a highly sensitive DC digital voltmeter and a highly stable DC constant current source. The measurement result is directly displayed by LED numbers. It is divided into 3 windows: voltage display window, material thickness display window (user input based on actual measurement), resistivity display window. The instrument has the characteristics of high measurement accuracy, good stability, compact structure, convenient use, etc., and it fully meets the requirements of international and national standards. The instrument is suitable for cable factories, conductive rubber and plastic material factories, computer factories, electronic watch factories, colleges and universities, scientific research and other departments. It is a necessary test equipment for the resistance performance test and process detection of conductive rubber and plastic materials and products. Technical parameter: Measuring range: When measuring semiconducting resistivity: resistivity 10-4--105Ω-cm; resolution 10-6Ω-cm When measuring other (wire and cable) resistance: resistance 10-4--2X105Ω, resolution 1uΩ Digital voltmeter: 1.
