Product Description

Best Application:

Brinell hardness tester for metallic materials.

General Summary

On the market for over 70 years, King Brinell hardness testers are lightweight, easy to maneuver and require only one operator, making them ideal for use as portable or bench units.


This test method includes requirements for the use of portable Brinell hardness testing machines that measure Brinell hardness by the Brinell hardness test principle and can meet the requirements of this test method, including the direct and indirect verifications of the testing machine.


Versatile enough to test virtually any size and shape of metal specimen, these testers are easy to use. The operator simply places the specimen between the anvil and the test head, cranks the test head down onto the specimen, locking the tester in place, closes the pressure release valve, and pulls the hydraulic lever until desired load is reached.

The tester applies up to a 3,000 kg load on a 10mm ball, making a lasting impression, which is available for re-reading at any time. A by-pass valve is automatically activated at the calibrated load, eliminating the chance of overloading. The impression is then read and recorded by the operator using a Brinell microscope such as "Deep reading microscope" or KingScan®IV automatic Brinell microscope. This portable Brinell hardness tester meets all international standards for Brinell testing including ASTM E-110, British Standard #240, Pt.2, Sect.1 and JIS Standards, and is calibrated to 1/2 of 1% of load on equipment traceable to NIST Standards.

Load Application


Tester Base Capacity

4” horizontal reach and 13.5” vertical (larger bases available)

Optional Adapters and Component Parts


Chain Adapter

Used for large cylinders it fits onto a standard test head and wraps around specimens that are too big for regular tester. High strength chrome /  molybdenum steel arms hold the chain to the test head and allow it to stay rigid while the chain takes the full thrust of the load. Supplied with 4' chain

Standard Test Head with Long Ram

Same features as standard test head plus a long ram that puts impression head at end of 2" extension for easy access into recessed areas or over raised edges.



Reverse Direction Load Adapter

Used inside pipes, tubes and other interior locations that are otherwise impossible to reach. Consists of an anvil which drops into the base and contains a 10mm ball penetrator; and a reverse direction load head, which screws onto the ram.

Low Pressure Test Head

Applied load and indicator dial are coordinated for softer metals. Can be calibrated to release at loads of 62-1/2 kg, 125 kg, 250 kg, 500 kg, or 1000 kg.


Adapter to Hold Test Head Upright without Base

For testing large flats it enables test heads to be used under large drill presses, boring mills, arbor presses and beams that are capable of withstanding 3000 kg.

Low Pressure Test Head with Long Ram

Same features as low pressure test head plus a long ram that puts impression head at end of 2" extension for easy access into recessed areas or over raised edges.


Standard Test Head

Calibrated accurate to 1/2 of 1% load. Releases at 3,000 kg automatically. Capable of incremental loads


14" base with 14" test height opening and 4" throat is standard. Optional 6" throat with either 14" or 20" test height opening available. 20" base also available with 4" throat and 20" test height opening.


2.5 & 5mm Ball Adapter

Used on softer materials or where a smaller impression is desired.
