The UNI-T UT3510+ series includes two models: UT3513+ and UT3516+. Adopting Kelvin 4-wire measurement principle, it eliminates lead resistance interference for precise micro-resistance testing. Equipped with 4.3-inch TFT color LCD, 4.5-digit display, 0.05% top accuracy and 1 μΩ minimum resolution, the maximum test speed reaches 10 ms per reading (100 readings/sec). It supports multiple test modes, temperature compensation, 6-bin comparator sorting, U disk data storage, and full communication interfaces, widely used in laboratory R&D and automated production line resistance screening。
