Fuel Cell Dedicated Tester

The AT526 series is a newly designed high-precision, high-stability battery tester. It can quickly and accurately measure the voltage and internal resistance of UPS lead-acid batteries (and virtually all types of batteries) during operation. Optimized specifically for measuring the high-voltage internal resistance of fuel cells, its internal signal source enhances anti-interference performance, significantly reducing interference from fuel cell load devices and enabling stable testing even under high-current conditions.

The AT526 series is a high-performance, intelligent instrument widely used for fuel cells, lead-acid batteries, lithium batteries, button cells, contact resistance, battery voltage, and internal resistance testing. It features professional sorting functions with configurable alert tones, making it ideal for automated sorting systems and fully automated production line testing.

The instrument includes a built-in RS-232C interface and supports optional ONMEAS USB232 and RS485 interfaces (SCPI compatible). Paired with the ONMEAS data acquisition software, it offers database functionality and Excel export capabilities, enabling efficient remote control, data acquisition, and analysis.
