ST2643 Ultra-high Resistance Microcurrent Tester

Overview 2.1 Basic Functions and Standards: The ST2643 ultra-high resistance microcurrent tester (high-resistance type body resistivity and surface resistivity tester) is a multi-purpose comprehensive measurement device that measures the volume resistivity and surface resistivity of solid sheet, thin film conductive electrostatic materials and insulating materials based on the principle of the annular three-electrode method. It can also be used as an ultra-high resistance meter or microcurrent tester. The design of this instrument complies with the national standard GB/T 1410-2006/IEC 60093:1980: "Test Methods for Volume Resistivity and Surface Resistivity of Solid Insulating Materials". 2.2 Complete set of instrument composition: It consists of the ST2643 high-resistance meter main unit, the standard ring-shaped three electrodes, connecting cables and other parts. The main unit is mainly composed of a high-voltage power supply, a microcurrent detector and an embedded single-chip micr…
