Fluke battery analyzers are the ideal test tool for maintaining, troubleshooting and
performance testing the individual stationary batteries and battery banks that are used in
critical battery backup applications in data centers, telecom networks, power distribution
systems and more. With an intuitive user interface, a compact design and rugged
construction, the Fluke battery analyzers provide optimum performance, test results and
reliability.
The Fluke 500 Series Battery Analyzers cover a broad range of battery test functions,
from ripple voltage to multi-measurement mode, which shortens test times by performing
three measurements in one: dc voltage, internal resistance tests and infrared temperature
measurement.
Fluke Battery Analyzers
By reducing testing complexity, simplifying testing workflow and
incorporating an intuitive user interface, the Fluke BT510 Basic Battery
Analyzer, BT520 Battery Analyzer and BT521 Advanced Battery Analyzer
bring a new level of ease of use for testing stationary batteries of all types.
• Key measurements: Internal battery resistance, dc and ac voltage, dc and ac current,
ripple voltage, frequency and temperature
• Sequence measurement mode: Automatic or manual sequence testing of battery strings
with automatic measurement storage including voltage, resistance and temperature (with
BTL21 intelligent test probe), eliminating the need to press a button each time a measurement
needs to be saved
• Comprehensive logging: All measured values are automatically captured during testing
and can be reviewed on the instrument before downloading for on the-go analysis
• Optimized user interface: Quick, guided setup and profile creation ensures the right data
is captured every time, and the combined visual and audio feedback cues reduce the risk
of measurement confusion
• Safety rating: CAT III 600 V
