Powder resistivity testerThis resistivity tester is an instrument used to measure the conductivity of carbon materials. This instrument adopts a hydraulic transmission system as the loading mechanism, with a large transmission ratio and smooth loading. It is equipped with an automatic display pressure standard dynamometer, a high-precision stable current source power supply, automatic display of current and voltage, and is stable, accurate, intuitive, and convenient. This instrument can be used to test the electrical resistivity of powdered materials according to ISO 10143-1995 and YS/T 587.6.
