Working since 1908

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 quickly took the reins and expanded the company as it became the Warren-Knight Instrument Company.

Over the past 100 years of Warren-Knight’s growth the company became a continuing reflection of our “in-the-field” knowledge gained from our customers and W-K’s dedication to engineering, product development, and service.

For many years, the Company manufactured and operated at its center-city Philadelphia location at 136 North 12th Street. In 1963, due to expansion of our manufacturing and our need to keep pace with customer requirements, the manufacturing plant and offices were relocated to their present facility in Northeast Philadelphia. The modern one-story building permits space and security needed to house the necessary automated equipment and tools required to provide the high level of quality demanded by our customers.

The 2045 Bennett Road location houses Warren-Knight Instrument Company and our retail service company, North American Survey Supply Company. NASS’s goals are to provide a similar service to the survey and engineering industry; however, NASS’s focus is on distribution of products manufactured from around the world.
