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 nearly all battery types) under working conditions, while also being optimized for high-voltage internal resistance measurement of fuel cells. The built-in 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 in fuel cell, lead-acid battery, lithium battery, button cell, contact resistance, battery voltage, and internal resistance testing. It features professional sorting functions with configurable buzzer alerts, making it ideal for automated sorting systems and fully automated production line testing.
The instrument comes with a built-in RS-232C interface and optional ONMEAS-dedicated USB232 and RS485 interfaces (SCPI compatible). Using ONMEAS data acquisition software, it offers database functionality and Excel export capabilities, enabling efficient remote control and data acquisition analysis.
