Product Details

Fluke BT521 Battery Analyzer

The Fluke BT521 Battery Analyzer (the Product) is a multifunctional meter designed for the test and measurement of a stationary battery system. The Product can measure the battery internal resistance and voltages. These measurements can be used to determine the overall condition of the system. It can also measure electrical parameters for battery system maintenance, including DC voltage up to 1000V, AC voltage up to 600V, and ripple voltage

Battery Voltage - During the internal resistance test, Fluke Battery Analyzers also measure the voltage of the battery under test
