With the introduction of new quality control requirements, accurate and reliable hardness testers are needed today more than ever.

The King Brinell Hardness Tester is designed to create indentations used to measure the hardness of metal materials. As a universally recognized testing instrument, the portable King Brinell offers several advantages:

 

• Permanence – Indentations can be checked and rechecked at any time.
• Accuracy – Calibrated to within ±0.5% of the applied load. It can be used with loads up to 3,000 kg and penetrates through surface heat treatment to evaluate the core material.
• Durability – Some portable King Brinell testers have been in service for more than 60 years.
• Versatility – Can be used in virtually any position: upright, upside down, or sideways. Bring the tester to the metal, not the metal to the tester.

 

For more than 60 years, King Brinell Hardness Testers have been lightweight, easy to maneuver, and require only a single operator, making them ideal for both portable and bench-top applications. Versatile enough to test virtually any size and shape of metal sample, King testers are simple to operate.

The operator simply places the specimen between the anvil and the test head, cranks the test head down onto the specimen, locks the tester in place, closes the pressure release valve, and pumps the hydraulic lever until the desired load is reached.

 

The tester applies loads of up to 3,000 kg through a 10 mm ball indenter, creating a permanent indentation that can be re-measured at any time.

A bypass valve automatically activates at the calibrated load, eliminating the possibility of overloading. The indentation is then measured and recorded by the operator using a Brinell microscope, such as the King Deep Reading Microscope or the Kingscan Automatic Brinell Microscope.

 

The Portable King Brinell Hardness Tester complies with all international Brinell testing standards, including ASTM E-110, British Standard No. 240, Part 2, Chapter 1, and JIS standards. It is calibrated to within ±0.5% of the applied load using equipment traceable to NIST standards.
