FT-701 Electrical Carbon Product Resistance Tester I Meet the standard: JB/T8133.2-1999 Test Method for Physical and Chemical Properties of Electric Carbon Products II Scope of application: This standard is applicable to the determination of electrical resistivity of electric brushes and other electric carbon products III Function description: The DC constant current source output system is combined with integrated circuits and high-precision chip control. The large LCD display screen is more intuitive, with direct reading of resistance, voltage drop, resistivity, and high-precision testing range; Various parameters and function settings are implemented through thin film panels, with a user-friendly design that conforms to ergonomic principles and provides USB, 232, and 485 communication interfaces; It can connect printers, computers, and other external control units, and configure PC software to obtain more process data. Testing report processing, storage, and data analysis are helpful 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 improving product quality A resistivity measuring device with a contact electrode made of elastic copper wire mesh; The test probe is made of stainless steel 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
