Description
The FNIRSI HRM-10 Battery Voltage and Internal Resistance Tester is a compact and versatile testing instrument designed to quickly evaluate battery condition. It can measure battery voltage and internal resistance at the same time, allowing users to identify batteries that may have degraded or are no longer performing properly.
The HRM-10 uses a Kelvin four-wire measurement method to reduce the influence of lead and contact resistance, helping improve measurement accuracy. Users can select automatic or manual measurement ranges depending on their testing requirements.
Equipped with a high-definition TFT color display, the tester presents measurement results clearly and makes it easy to monitor voltage and resistance values. It also supports sorting, history records, user calibration, and data export, making it useful when testing and comparing multiple batteries.
The device supports voltage measurements up to 100V DC and resistance measurements up to 200Ω. Its rechargeable 1000mAh lithium battery and USB Type-C charging interface make it convenient for portable testing in workshops, laboratories, battery repair, and automotive applications.
