Operate these testers with one hand. Squeeze the handles until the penetrator contacts the test material and a reading appears on the dial indicator.

Test hardness right on your production floor. Unlike benchtop testers, these portable ones don’t require you to move large or hard-to-access parts. They use an indenter to measure the hardness of aluminum, brass, and steel. These testers can be used at any angle without affecting accuracy.

For heat-treated material harder than Rockwell C20, use the optional C-scale diamond indenter.

Make sure your hardness testers are accurately calibrated. Blocks are marked with their corresponding Rockwell hardness and a serial number.

All blocks come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Quickly test large parts or metal bar stock with our most precise hardness testers. These testers are portable and can be brought to facilities and jobsites to test items that are too large to move. While some hardness testers only work on one type of metal, these testers work on most metals. They have a rebound hammer that bounces back after impact—the distance it rebounds indicates the hardness of your surface. To obtain accurate readings, steel and other hard metals must be at least 1” thick and aluminum and other soft metals must be at least 3” thick.

Convert your measurements between Rockwell, Vickers, Brinell, or Shore hardness ratings. Your readings will show on a backlit digital display so you can test even in low light. Store up to 100 measurements with their built-in memory or transfer the data to your PC using the USB port.

Determine the hardness of very hard steel. To use, slide a test bar into the tester, place the tester on your surface, and hit with a hammer; a steel ball will make an impression. Measure the impression with the 20X microscope and use the computing disc to determine hardness.

Finding your Brinell hardness doesn’t have to be so hard—these scopes scan and measure indents, then calculate the hardness for you. Accurate and efficient, these scopes replace the need for bulky microscopes and manually measuring and calculating hardness. Connect these scopes to your computer and use the included software to see a live image of the indent on your screen. You can zoom in 4X and adjust the focus to capture a wide range of indent diameters. To fine tune the automatic measurement, simply drag your cursor. Use the software to set test parameters, convert the value to other hardness scales, and validate the test results. The software also marks any measurements that fall out of your set specifications. When you’re finished, you can generate a customizable Microsoft Word or Excel report for your records.
