FLUKE BT520 Battery Analyser
- Built for tough-to-reach testing
The FLUKE BT520 Battery Analyser is designed to make battery testing faster, easier, and more reliable—even in tight or awkward spaces. Whether you work in a data centre, telecom room, or industrial power system, this tool helps you carry out critical battery maintenance, performance checks, and troubleshooting on both individual batteries and full battery banks.
It’s compact, durable, and smart—made for professionals who need accurate test results they can trust.
What Makes the FLUKE BT520 Stand Out?
The FLUKE BT520 is built with features that help you measure battery systems located inside cabinets or other hard-to-access spots. It comes with the BTL20 Intelligent Test Probe Set, which includes long and short extenders, a built-in screen, and an audio speaker. This makes it easy to see and hear your readings while working in cramped or dimly lit areas.
With the push of a button on the probe, you can automatically log voltage readings—so you don’t have to juggle the analyser while trying to take a reading.
