Fluke BT520 Battery Analyzer
Fluke BT520 Battery Analyzer
Fluke Battery Analyzers allow you to quickly and easily define upper and lower measurement thresholds or tolerance ranges. During the testing process, measured values are automatically compared to the predefined threshold levels producing a PASS, FAIL or WARN indication after each measurement. The intuitive user interface, compact design and rugged construction ensure optimum performance, test results and reliability.
