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.
