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 battery types) under operating conditions. It is also optimized for high-voltage internal resistance measurement of fuel cells. The internal signal source enhances anti-interference performance, significantly reducing interference from fuel cell load devices, ensuring stable testing even under high-current test 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 battery internal resistance testing. It features professional sorting functions and beep settings, suitable for automatic sorting systems to complete fully automated production line testing.
The instrument comes standard with an RS-232C interface and optional Onmeas USB232 and RS-485 interfaces (SCPI compatible). Using the Onmeas data acquisition software with database functionality and Excel export, it enables efficient remote control, data acquisition, and analysis.
