Internal resistance tester UHV-750

battery

The UHV-750 Battery Internal Resistance Tester is a portable instrument for measuring battery internal resistance and terminal voltage using advanced AC discharge testing methods. It supports fast online measurements, data storage and analysis for efficient battery fleet management.

Main functions

• Quick measurement of battery voltage, internal resistance, connection resistance and optional oscilloscope parameters online.
• Alarm when internal resistance or terminal voltage exceeds preset limits.
• Anti-AC ripple-noise circuit technology to improve measurement accuracy and repeatability.
• Fast re-test function allowing repeat measurement and automatic overwrite of original data in case of human error.
• Prestores more than 200 reference internal resistance values; values are customizable.
• Battery parameters are grouped and numbered for convenient data management.
• Supports PC-based intelligent battery-status analysis software for tracking historical records, status curves, comparative analysis and graded management.
• Automatic test mode with automatic analysis/judgement of deteriorated battery state and batch management (excellent/good/medium/poor).
