      AT525 storage battery internal resistance online tester adopts high-performance 32dgt ARM micro processor, can be used to test voltage and internal resistance of battery. Test the resistance 0.001mΩ~3.3000Ω, 0.0001V~60.000V DC voltage with the resistance max reading of 3300dgt and voltage 60,000dgt. Accuracy of 0.5% even the speed is under 10 times per second. The indication beat is controlled under 3 digits. AT525 can test open-circuit voltage accurately, adding automatic sorting function and beep set, is applied to UPS online batteries measurement, automatic sorting system to complete production line test. Equipped with USB interface, can be used for remote control, data acquisition and analysis. It is suitable for flow line inspect of storage batteries.
