Overview
Emissions And Stack’s high precision LCR meter 20Hz to 5MHz with TFT LCD is designed for advanced electronic testing in laboratories and production facilities. It provides wide frequency coverage, fine resolution, and excellent accuracy of up to 0.05%, ensuring stable and reliable component measurements. The device supports inductance, capacitance, resistance, and impedance testing, with the ability to simultaneously display multiple parameters. Engineers can perform advanced functions such as graphic scanning analysis, frequency/level/bias sweeps, and built-in comparator testing. Equipped with RS232, USB, handler, and optional GPIB interfaces, it can be easily integrated into automated testing environments. The large 7-inch TFT LCD screen provides clear visualization of results, while the multiple test modes, calibration functions, and storage options enhance usability. With fast measurement speed, wide display range, and flexible trigger modes, this meter is ideal for R&D, quality control, and manufacturing.
