FLUKE BT521 Battery Analyser with Wireless Communication

 

Looking for an advanced battery analyser?  The FLUKE BT521 battery analyser is designed to make battery monitoring more efficient and effective, and is the ideal test tool for your maintenance program of individual, stationary batteries and battery banks.  Specifically designed for measurements on stationary batteries of all types, including gel AGM, lithium-ion and wet-cell lead-acid batteries.

 

Handy hardware features of the BT521

On the front you‘ll find control buttons and an easy-to-use rotary switch for making measurement mode selection. The side USB port is used to download data to your computer so you can compare measurement results and trends, and generate battery analysis reports.

The smart battery utilises built-in LEDS to indicate the batteries current state of charge so you can easily check its status.  Hanging straps located on both top and bottom of the unit are used for the magnetic hangar, hanging harness, or carrying harness. The main measurement input for all parameters, to the instrument, is via the multi-pole connector on the top of the instrument.  The BTL10 probe is a simple two prod probe with a kelvin connection. The insulated centre pin carries current, while the outer pin measures voltage.  Voltage drop caused by the test current draw is zeroed out by the kelvin connection nullifying its effects.

 

FLUKE BT521 Key Features:

  • Key measurements: Battery resistance, dc and ac voltage, dc and ac current, ripple voltage, frequency and battery 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).
  • Comprehensive logging: All measured values are automatically captured during testing and can be reviewed on the instrument before downloading for on the-go analysis.
  • Optimised user interface: Quick, guided setup ensures you‘re capturing the right data every time, and the combined visual and audio feedback cues reduce the risk of measurement confusion.
  • Threshold comparison: Configure multiple reference values and thresholds for resistance and voltage. Comparison result feedback after each measurement via visual and verbal cues.
  • Ergonomic test leads: Rugged coaxial two pole kelvin test pins with remote SAVE button reduce test time and increase efficiency.
  • Test probe extenders: Long reach probes for double stacked cells.
  • Intelligent test probe set (BT520 and BT521): Integrated LCD display, infrared temperature measurement (BT521 only), flashlight, verbal audio feedback and captures voltage readings and temperature logging automatically or via integrated save button.
  • Enhanced data analysis: Quickly compare trends, analyze results and create reports with included battery management software.
  • Easy reporting: Generate PDF report on the PC software with analysis graphics and data table or quick email format report with csv file on the mobile app.
  • Wireless communication: For data download and remote display while measuring. Browse and email measurement data via iOS app.
  • Battery life: 7.4 V 3000 mAh lithium-ion battery for more than eight hours continuous operation.
  • USB port: For fast data download to supplied data analysis and report management application software.
  • Highest safety rating in the industry: CAT III 600 V, 1000 V dc max. rated for safe measurements all around the battery power supply equipment.
