Carbon resistivity testerIntroduction:

one.The four probe testing method is used to measure the high conductivity of carbon materials, graphite and other block shaped rod-shaped and powder materials at room temperature. This instrument adopts a high-precision constant current and constant voltage source, which automatically displays current and voltage and automatically switches the test range according to the characteristics of the tested product, without the need for manual adjustment and setting.4.3LCD screen display, automatically displaying test current, voltage, temperature, resistivity and other data. Optional: If equipped with software, the instrument can be operated through the software to obtain test data charts and test results. Test fixtures can be selected according to different product shapes.
