Intelligent Resistivity Tester Bulk Resistivity Meter for Graphitized Coke Powders

1.Description:

This instrument complies with the requirements of GB/T24521-2018 "Method for Measuring Resistivity of Carbon Raw Materials and Coke". It is a specialized instrument for measuring the resistivity of coke, graphite, calcined fines, calcined anthracite and similar powder materials. The instrument is powered by a high-precision constant current source, with automatic display of current and voltage. It adopts computer-based fully automatic measurement and control, featuring high accuracy and simple operation. It is suitable for use in universities, research institutions, quality inspection and production enterprises.

2.Working principle

Place a certain-sized dry sample into the sample chamber, introduce a certain intensity of current under a certain pressure, measure the voltage drop at both ends of the sample, and calculate the resistivity of the sample based on Ohm's Law.

3.Configuration:

Including one LRWD-II test host, one set of sample fixtures, one set of test software, one data cable, and one computer (configured as per the contract).
