Electric brush resistivity tester

Electric brush resistivity tester

Reference standard:

JB/T8133.2-1999 Test Method for Physical and Chemical Properties of Electric Carbon Products

two.Scope of applicationApplicable range：

This standard is applicable to the determination of electrical resistivity of electric brushes and other electric carbon productsthree.Function DescriptionFunction deion：

DC constant current source output system combined with integrated circuit chip control, LCD display screen, direct reading resistor, voltage drop, resistivity; Parameter and function settings are implemented through thin film panels, providing USB and 232 communication interfaces; It can connect printers, computers, and external control units. Optional PC software can obtain process data, test report processing, storage, and data analysis for product development and quality control Under PC software, current, resistivity, resistance, and voltage drop curves and data models can be obtained to establish a database for product quality The test probe is made of tungsten needle material, with a spacing deviation of 1%. The sample size is 10 * 10 * 64mm, and the probe spacing is 25mm; 4 * 8 * 32mm probe spacing is 16mm
