Uni-T Battery Internal Resistance, Voltage, and Temperature Tester UT677A

Description

The Uni-T UT677A is a professional battery internal resistance tester employing the AC 4-terminal measurement method at 1KHz to deliver accurate resistance readings from 0.001mΩ to 3Ω — completely unaffected by contact resistance between test leads, terminals, and battery electrodes. With 1μΩ resolution at the lowest range, ±0.5%FS accuracy across most ranges, simultaneous voltage measurement up to 71V, and NTC temperature sensing from -10°C to +60°C, it provides a comprehensive health assessment for lead-acid batteries, lithium batteries, and ESR parameters of electrolytic capacitors. Bluetooth connectivity, USB interface, PC software, 5000-reading storage, and programmable PASS/WARNING/FAIL thresholds make it the benchmark tool for battery production, installation, solar energy systems, and industrial maintenance environments.
