There are a variety of portable hardness tests available, some of which are better suited for particular applications than others. Depending on what you needed to know and why you would choose the right hardness tester for the job.

Telebrineller testers. These testers compare the indentation left by a steel ball in a standard bar with the indentation left by the test material to determine the hardness. Consumable standardized bars that are close to the test material’s hardness should be used. Although the procedure is rather simple, it would have the same restrictions as the rebound testing approach.

To demonstrate a loss in strength in damaged areas of a structure compared with undamaged areas or virgin material, a Barcol hardness tester for use on Al alloys is typically utilized as a comparison tool. Barcol hardness testers are excellent for this type of comparative study and are relatively portable, although the conversion to harder scales is only approximate.

NextGen’s Telebrineller Brinell Hardness Testing System is the most solution on the market for portable hardness testing.
