The Webster Hardness Tester is a portable, fast, accurate hardness gauge that is made in three distinct models for testing aluminum, brass, copper, and mild steel. The Webster Hardness Tester will quickly identify tempers and test a variety of shapes that other testers cannot check, such as extrusions, tubing, and flat stock.
Each tester model operates in the same manner but differs only in penetrator design, type of load spring, and hardness ranges. The principle of operation is simple. The work to be tested is placed between the anvil and the penetrator. Pressure is then applied to the handles until the "bottom" is felt at which time the dial indicator is read.
Applications for Webster Hardness Testers Are:
Identifies heat-treated parts from non-heat-treated parts.
Provides correlation between a bench-mounted hardness tester and the production line.
Segregates materials in stock.
Differentiates between soft or work-hardened material.
Identifies parts made from improper or substandard alloys.
Checks for proper heat-treatment response.
Useful in conjunction with stationary laboratory hardness testers.
Gives a rapid 100% check on parts which would consume many man hours with slower-operating test equipment.
Can be used on assemblies that cannot be brought to the labs.
Webster Hardness Testers Features:
One-hand operation and portability.
Round 3/8-inch diameter anvil permits testing a great variety of shapes.
Simple operation permits readings independent of the operator's skill.
Test is made by simply applying pressure to the handles until the "bottom" is felt.
Easy-to-read dial indicator with 20 graduations permits use of the tester as "go" and "no-go" gauge.
Standard hardness gauge tests materials up to 1/4 inch in thickness.
