FNIRSI HRM-10 Battery Resistance Tester

From the shop's description

FNIRSI HRM-10 Battery Resistance Tester FNIRSI® HRM-10 Battery Resistance Tester is a professional portable instrument developed for accurate measurement of battery internal resistance and voltage parameters. Designed for lithium battery diagnostics and battery performance evaluation, the HRM-10 utilizes four-terminal Kelvin testing technology to minimize lead resistance interference and improve low-resistance measurement accuracy. Features: True four-wire (Kelvin) measurement topology for accurate internal resistance readings. Simultaneous display of internal resistance and voltage values on a single screen. Automatic range selection with manual override capability for flexible operation. Eight-group sorting mode with user-defined pass/fail thresholds for battery grading. Automatic PASS/FAIL verdict display during sorting operations. Internal history record with automatic saving of all measurement and sorting data. USB-C mass-storage data export to PC as spreadsheet files. Independent calibration for voltage and resistance ranges. Factory reset function to restore original calibration parameters.
