Product Description
Introduction to Xiangtan Xiangke WDT-II Intelligent Graphite Resistivity Tester:
I. Overview:
This instrument conforms to the requirements of GB/T24521-2018 Method for Determination of Resistivity of Carbon Raw Materials and Coke and GB/T24521-2009 Method for Determination of Resistivity of Coke. It is used to measure the resistivity of coke, graphite, calcined coke, 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 adopts computer-controlled fully automatic measurement and control, featuring high precision and ease of operation. It is suitable for use in universities, research institutes, quality inspection institutions, and production enterprises.
Instrument Testing Principle:
A certain amount of dried sample with a certain particle size 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.
