Overview
The FR HRM-10 is a professional-grade Internal Resistance (IR) tester that uses the 4-wire Kelvin method to eliminate the resistance of the test leads themselves, ensuring laboratory-level accuracy. Whether you are matching 18650 cells for a power wall, checking the health of a car battery, or testing high-discharge LiPos for a drone, the HRM-10 provides instant, reliable data.
Key Features
True 4-Wire Measurement: Uses Kelvin clips/probes to ensure the resistance of the wires doesn’t interfere with your ultra-low milliohm readings.
Internal Resistance Specialist: Measures down to 0.01mΩ, allowing you to spot even the slightest degradation in high-capacity cells.
Multi-Chemistry Compatible: Works with Lithium-ion (18650/21700), LiFePO4, Lead-Acid (AGM/Gel), Ni-MH, and Ni-Cd.
Dual Display: Simultaneously shows Voltage (V) and Resistance (R) on a sharp, backlit LCD screen.
Sorting Mode: Built-in sorting function helps you quickly group batteries with similar resistance—essential for building balanced battery packs.
