Powder Resistivity Tester
Published: 1/6/2025
Bench-top system for measuring electrical resistivity of carbon and other powder materials under controlled compression. Complies with ISO 10143:1995 and YS/T 587.6 for standardized powder resistivity testing with automated display and data handling.
Product Description
The DCY3F Powder Resistivity Tester measures the electrical resistivity of powder and granular carbonaceous materials by applying a defined compressive load and sourcing a stable current while monitoring voltage drop. A hydraulic drive provides smooth, high-ratio loading to ensure consistent packing density, and a pressure-indicating force gauge enables accurate control of applied pressure.
A high-precision constant current source powers the measurement, with automatic display of current and voltage for straightforward operation. The system supports standardized test geometries and electrode spacings and is equipped with a fully automatic touch-screen measurement and control interface for data processing and printing of test results in accordance with ISO 10143:1995 and YS/T 587.6.
