About Warren Industries, Inc.

In 1908 C. F. Iszard and J. Henry Warren started the Iszard-Warren Company to design, manufacture, and sell precision surveying, engineering, and scientific instruments. In 1913 J. Henry Warren took the reins and expanded the company as it became the Warren-Knight Instrument Company.

Over the past 100 years, Warren-Knight's growth has reflected the in-the-field knowledge gained from customers and its dedication to engineering, product development, and service. For many years the company operated at 136 North 12th Street in center-city Philadelphia. In 1963, expansion and changing customer requirements moved the manufacturing plant and offices to the present Northeast Philadelphia facility, with space and security for the automated equipment and tools required to maintain quality.

The 2045 Bennett Road location houses Warren-Knight Instrument Company and North American Survey Supply. Warren-Knight manufactures precision instruments and systems; NASS distributes products manufactured around the world to the survey and engineering industries.

Warren-Knight supports aerospace, engineering, meteorological, metrological, nautical, and surveying applications. Its technical teams have worked with the U.S. Department of Defense, NASA, the International Civil Aviation Organization, the National Weather Service, FAA, NATO, and the Army, Navy, and Air Forces, as well as research institutes and universities.
