The REED R5001 is an autoranging LCR meter that measures inductance, capacitance, and resistance along with secondary readings like dissipation factor, quality factor, phase angle, and ESR. It supports 4- and 5-terminal Kelvin measurement for high accuracy, is rated IP67 for dust and water resistance, and includes a backlit display with data hold and relative modes. A full accessory kit of test leads, tweezers, alligator clips, and batteries is included.
