It is suitable for universities, research institutes, quality inspection and production enterprises.
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.
WDT-II Graphite Resistivity Tester Main Technical Parameters:
1. Resistivity Measurement Range: 40-4000 (uΩm)
2. Precision:
3. Repeatability: Under repeatable conditions, the difference between two measurements of samples greater than 300uΩ·m is no more than 5%, and the relative deviation between two measurements of samples less than 300uΩ·m is no more than 8%.
4. Reproducibility: Under reproducible conditions, the difference between two measurements of samples greater than 300uΩ·m is no more than 8%, and the relative deviation between two measurements of samples less than 300uΩ·m is no more than 10%.
5. Constant Current Source: Output voltage 0-24.0000V, output current 0-1.00000A
6. Voltage Range: 0-100.00mV or 0-1000.0mV
7. Pressure Range: 0-1000.0N
8. Displacement Range: 0-40.00mm
9. Loading Method: Electric Loading
10. Measurement and Control Method: Connected to a computer for automatic control, data processing, and generation of test reports, with print output.
11. Sample Tube: Inner diameter 16.0mm~16.3mm
12. Voltage: 220V, 50HZ
Instrument Configuration: Includes one WDT-II testing host, one set of sample fixtures, one set of testing software, one set of data cables, and one computer (configured according to the contract).
