Description
Overview
GAOTek high-precision digital LCR meters are high-precision LCR meters with basic accuracy of 0.1% and 0.05% and a maximum measurement frequency of up to 500 kHz. The 5-digit 4.3 in (10.92 cm) TFT LCD display gives easy reading. The RS-232 interface facilitates remote control and analysis of measurement results. With its fast measurement speed, wide frequency range, and low cost, this product is widely used in R&D, IQC, online quality control, and automatic test systems.
