# QuadTech Test Equipment

Established in March 1991, QuadTech developed out of the purchase of General Radio’s (GenRad’s) Precision Instrument Division. The team of experts from GenRad that transferred to QuadTech enabled the new company to grow rapidly and build off of the old brand’s more than 100 years of experience. QuadTech is a manufacturer of impedance analyzers, insulation meters, fixtures, power supplies, and electronic loads. In 2012, the company partnered with Chroma ATE as its main manufacturer of high potential (hipot) and other test equipment. Consumers can still purchase used and refurbished devices and instruments that carry the QuadTech brand name from ValueTronics.com.
