Maury and Associates began in 1957, when Mario A. Maury and his sons started a microwave test equipment and calibration manufacturing company in Montclair, California. The company developed a comprehensive product line of precision instruments and accessories, growing to satisfy the needs of its consumer base. After almost 60 years of business and a brand name change, Maury Microwave Corporation is still dedicated to meeting consumer needs with exceptional laboratory devices, system components, impedance tuners, noise parameter system, calibration kits, and interface equipment. Maury is a name that engineers trust. Shop for used, professionally refurbished Maury Microwave products and kits at ValueTronics.
