AT528 Handheld Digital Battery Meter with TFT True-Color LCD Display Battery Internal Resistance Tester

AT525 handheld battery tester adopt high-performance 32dgt ARM micro processor, can be used to test voltage and internal resistance of battery, it is upgrade version of AT528, it is applied to UPS online measurement. Test the resistance 0.001mΩ – 3.3kΩ, 0.0001V - 60V DC voltage with the resistance max reading of 3300dgt and voltage 60,000dgt. The indication beat is controlled under 5 digits. AT525 can test open-circuit voltage accurately, adding automatic sorting function and beep set, is applied to 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.
