FNIRSI LC1020E

One of the key advantages of this model is its high measurement accuracy, automatic R/L/C component identification, and the ability to display two measurement parameters simultaneously. The FNIRSI LC1020E is a professional handheld LCR meter designed for measuring resistance, capacitance, inductance, and impedance. It supports five test frequencies, true four-wire (Kelvin) measurement, component sorting, data logging, and open/short calibration. Its high accuracy makes it an excellent choice for laboratories, production lines, electronics repair, and component quality control.
