The Extech 380193 Passive Component LCR meter is a favorite in manufacturing facilities for quality control and product testing, as well as for individual users that need to validate and sort a range of components in custom projects. Unlike the capacitance and resistance capabilities of a digital multi-meter, this affordable yet robust meter provides added accuracy and the advantage of inductance. For circuit testing, the LCR meter enables you to test a range of important parameters such as the quality factor, dissipation factor, and resistance of your components with both series and parallel modes.
