IET Labs, Inc. was founded in 1976 with a mission to provide cost-effective solutions for electronic component applications. Headquartered in Westbury, New York, USA, the company specializes in precision impedance instrumentation and electrical standards. In 2000, IET Labs acquired the GenRad standards, impedance decades, megohmmeters, digibridges, and audio/strobe lines, continuing to manufacture and support these classic products. In 2006, IET further acquired the esi resistance lines, merging two of the most legendary impedance companies with its own engineering expertise. Today, IET Labs manufactures 98% of its products in the United States, including nearly all major components. The company's product portfolio encompasses a wide range of impedance devices, from cost-effective decade boxes to the most important metrology standards. Key product families include the GenRad Tradition series (e.g., 1433 Decade Resistors, 1482 Inductance Standards), esi Resistance Standards (e.g., SR1010 Resistance Transfer Standards), and IET's own HARS-X precision resistance decades, HACS capacitance decades, and HALS inductance decades. IET also offers megohmmeters, Digibridge impedance meters, a
