AT528 Handheld AC milliohm meter
AT528 Minitype Handheld Micro ohm Meter adopts high-cost performance 32 bit micro-processor control, designed for large and middle lead acid battery. It can judge the degradation of the battery by testing the internal resistance and voltage of the battery. Test range from 0.01mΩ~2.000kΩ, 0 - 50 V DC voltage, max reading of the resistance of 2200 dgts and voltage of 5000 dgts.Accurate open voltage can be tested out by vectorless test theory. Professional sorting function and sorting sets of the beep make it's more suitable for automatic assembly line test.
AT528 has both portable of minitype and the excellent performance of the bench type. Optional USB interface which can be used for remote control and data acquisition and analysis makes it more suitable for assembly line test of all kinds of batteries.
