The PORTABLE K&M BRINELL HARDNESS TESTER is designed to make impressions that are used to measure the hardness of a metal. As a universally recognized tester, this unit has a number of advantages.

Permanence - Impressions can be checked and re-verified at any time.

True Brinell Values -Test forces are loaded by hydraulic pressure up to 500kgf, 750kgf, 1000kgf, 1500kgf and Max to 3000kgf. It delivers a true Brinell value based on the tried and true principle, not conversion value as other types of portable hardness testers.

Accuracy - Calibrated accurate to 0.5% of load. Can be used for higher loads up to 3,000 kgf. Breaks through surface heat treatment to get to the core of the material.

Durability – This type of tester has been in use for more than 60 years in US and abroad.

Versatility - Can be used in virtually any position: right side up, upside down or sideways. Take the tester to the metal, not the metal to the tester.

Accessories- Many available accessories for different conditions.

K&M Brinell hardness tester KHB-3000 is lightweight, easy to maneuver and requires only one operator, making it ideal for use as portable or bench units. Versatile enough to test virtually any size and shape of metal specimen, KHB-3000 is truly 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.  Closing the pressure release valve, and pulling the hydraulic lever until the desired load is reached enables the test to begin. The tester applies up to a 3,000 kgf 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 indention is then read and recorded by the operator using the KBT-10M or optical comparator / Microscope. The K&M Brinell hardness tester KHB-3000 meets all international standards for Brinell testing including ASTM E-10, ISO6506 and JIS Standards.
