- 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.

Available Models:
The Webster Hardness Testers are a portable, fast, accurate hardness gauge that are made in three distinct models for testing Aluminum, Brass, Copper and Mild Steel. Webster Hardness Testers will quickly identify tempers and test a variety of shapes that other testers cannot check, such as extrusions, tubing and flat stock.
All testers operate in the same manner but differ 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 "bottom" is felt at which time the dial indicator is read.
Standard Kit includes: Main Unit, fitted case with a spare penetrator, adjusting wrench, standard test strip and instruction manual

This cutaway view of a Webster Hardness tester shows the working parts common to all testers. Each tester is identified with a model and serial number stamped on the frame and should be mentioned in all correspondence relative to repair or when ordering parts. Penetrators should be examined periodically for wear and replaced with new ones.
Please note the following for replacement parts:
Penetrators and Load Springs differ with each model tester. All of the other parts are common to all three testers.
