JG2551 Battery Electrode Sheet Resistance Testing System

Overview 2.1 Basic Functions and Basis Standards: The JG2551 vertical specific resistance tester is a multi-purpose and intelligent comprehensive instrument that uses the four-terminal pin measurement principle to test the vertical body resistivity and vertical surface resistivity of coatings Measuring instruments. The design of this instrument complies with MIL-DTL-81706-2004 for chemical conversion materials of coated aluminum and aluminum alloys, and refers to GB/T20042.7- 2014 "Test Part of Carbon Paper for Fuel Cells",GB/T 20042.6 "Test of Resistance of Fuel Electrode Sheets" Pressurization section (sample testing section) : Manual pressure is provided up to 300kg. The pressure can be adjusted according to the actual situation. Contact area and pressure sensor are provided Targeted pressure and height selection. The upper and lower electrodes adopt gold-plated copper electrodes, which effectively improve the contact resistance between the test electrode and the sample. 2.2 Comple…
