AT2527B Energy Storage Battery Internal Resistance Tester

The AT2527B is a compact bench-top instrument featuring full-automatic real-time measurement, controlled by a high-performance 32-bit ARM microprocessor. It features a 5-inch true-color LCD touchscreen display with full-touch operation for an intuitive user experience.

The instrument measures resistance from 0.0001mΩ to 3.3kΩ and DC voltage from 0.00001V to 800.000V, with 33,000 display counts for resistance and 800,000 display counts for voltage. The AT2527B combines high precision, high resolution, and ultra-fast measurement capabilities, offering 0.5% resistance accuracy and 0.01% voltage accuracy with measurement speeds up to 55 t/s.

The newly improved AC resistance testing principle is suitable for internal resistance testing of virtually all battery types, including lithium-ion batteries, lead-acid batteries, button cells, and more, making it ideal for production line inspection.
