AT51X2

2-Channel Parallel DC Low Resistance Tester

CategoryMulti-Channel DC Low Resistance Tester SeriesAT51X Series

AT51X2 is a newly designed high-precision, wide-range multi-channel resistance tester for parallel measurement, capable of testing two resistance channels simultaneously.

It is controlled by a high-performance ARM microprocessor. The 3.5-inch true-color LCD display can show resistance values for all 8 channels simultaneously, and each channel can be configured with individual comparators.

Designed for automation equipment, it features RS-232C and HANDLER interfaces for OK/NG signal output, enhancing automated production testing capabilities.
