Webster Instrument is a fourth-generation, family-owned business that was founded by R.A. Webster in 1932. The WEBSTER™ hardness tester was developed during his years as the Chief of Inspection at the Douglas Aircraft Company. We remain owner-operated as we look into the future to continue building on our reputation for quality customer service.
The foundation of Webster Instrument was built on the reputation of our first customers, such as:
Boeing Airplane Co.
Douglas Aircraft Co.
Bureau of Aeronautics
Department of Defense
Hudson Motor Car Co.
We provide portable, fast, and accurate hardness testing products that are made in three distinct models for testing aluminum, brass, copper, and mild steel. These hardness testing products will quickly identify tempers and test a variety of shapes that other testers cannot check, such as extrusions, tubing, and flat stock.
