MOEORW-W3923 Battery Internal Resistance Tester

Product Introduction

The battery internal resistance tester features a color resistive touchscreen, enabling flexible and convenient operation via finger or stylus input. This digital storage-type multifunctional portable tester rapidly and accurately measures battery operational parameters. It performs online detection of individual cell voltage and internal resistance, storing and processing acquired data while alerting for battery faults to precisely and effectively assess cell health. The meter saves, queries, deletes, and exports test data. The host computer software analyzes and displays test data through various charts, automatically generating battery inspection reports.
