Graphite and Carbon Materials Electrical Conductivity and Resistivity Tester
The WDT measures the electrical conductivity and resistivity of carbon materials, graphite blocks, and carbon paper using a regulated voltage/current source with automatic current and voltage display. At room temperature, it is used to determine the resistivity of cathode blocks, prebaked anodes, anode and cathode pastes, and other carbon products with reference to ISO 11713-2000, YS/T 63.2-2005, and YS/T 64-1993.

Product Description
A regulated voltage/current source supplies the test circuit, with automatic current and voltage display. The test platform accommodates specimens with diameters of 20–50 mm and lengths of 80–130 mm and rotates through 360° for positioning.
The platform uses a digital caliper and a digital voltmeter for dimensional and electrical measurements. This page is a configuration overview; obtain a verified model-specific datasheet to confirm the resistivity/conductivity measurement range, accuracy basis, and specimen-fixture configuration before selection.
