BT521ANG-Lte Battery Analyzer with Angled Probes Only
SKU: FLUKE-BT521ANG-LTE
Fluke BT521 advanced battery analyzer with angled probes only (no temperature). Streamlined kit for applications where straight probes are not needed.
List price. Volume pricing available.
The Fluke’s first product for battery sorting, 6.5/7.5-digit voltmeter + high-accuracy battery tester + multiplexer cards - three-in-one, 7 major performance improvements
Key Features
- Higher Accuracy: 18 ppm accuracy for DC voltage; 0.2% accuracy for AC internal resistance
- Faster speed: 4 sampling speeds: Ex-Fast (10ms), Fast (20ms), Medium (100ms), and Slow (200ms); Scan mode - average 100 ms per channel
- More stable performance: can be used conjunction with SW9010 multiplexer cards with special loop design, reducing the effects of eddy current, improving immunity
- More load capacity: support the allowable total line resistance ≥ 10 Ω (for 3 mΩ measurement range), ≥20 Ω (for 30 mΩ or higher measurement range)
- More functions - built-in high-z mode for enclosure potential measurement
- High compatibility: support LAN and RS232 interface, and command set compatible with the similar products
- More friendly interface: 4.3-inch LCD screen, intuitive user interface
