Xiangtan Xiangke WDT-II Intelligent Graphite Carbon Resistivity Meter Graphite Coke Powder Resistivity Tester
Xiangtan Xiangke WDT-II Intelligent Resistivity Tester
I. Overview
This instrument conforms to the requirements of GB/T24521-2018, the method for determining the resistivity of carbon raw materials and coke. It is a special instrument for measuring the resistivity of coke, graphite, calcined coke, post-calcined smokeless coal, and similar powdered materials. The instrument uses a high-precision constant current source for power supply, with automatic display of current and voltage. It uses computer-controlled automatic measurement, featuring high precision and ease of operation. It is suitable for use in universities, research institutes, quality inspection, and production enterprises.
II. Principle:
A certain particle size of dried sample is placed in the sample cell. Under a certain pressure, a certain intensity of current is passed through, and the voltage drop across the sample is measured. The resistivity of the sample is calculated according to Ohm's law.
