Donart Electronics was incorporated in September 1959. For more than 40 years, the company has been serving industrial clientele in the United States and many foreign countries. The company is housed in a 6,000-square-foot building on two acres of land in McDonald, Pa. Approximately 1,200 square feet of the plant is used for offices and engineering facilities. All other remaining area is used for mechanical and electronic assembly and testing. Donart manufactures, sells and services a complete line of Ellipsometers, which is a quality control instrument used by the steel and aluminum industries for the measurements of thin oil films on tin plate and similar products. The company has been one of the leaders in the manufacturing of Ellipsometers since the early 1960s. Donart Electronics is privately owned and employs nearly 10 people.
