Durometer Hardness Testers
Measure the hardness of flat materials, such as plastic, rubber, and laminate. For more information about durometer scales, please see the bottom of About Rubber.
Style 2 testers have a narrow base for access to confined areas. You can hold them in your hand.
Style 3 testers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.
Mount these testers to an optional operating stand (sold separately) to make sure they’re parallel to your sample for accurate readings and repeatability.

Digital Durometer Hardness Testers
Measure the hardness of flat materials with a digital display. For more information about durometer scales, please see the bottom of About Rubber.
These testers come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. A maximum-reading indicator holds the highest reading until reset. Use the USB/RS-232 port for direct connection to your PC.
Mount the tester to an operating stand (sold separately) to ensure it is perfectly parallel to the sample. This reduces error and gives accurate, repeatable readings.

Durometer Hardness Test Block Sets
Confirm your durometer hardness tester is taking accurate readings. Use your tester on these blocks to make sure the durometer readings match the block. The blocks come with a calibration certificate traceable to NIST to ensure their accuracy.

Portable Digital Hardness Testers
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.

Ultrasonic Portable Hardness Testers
Using ultrasonic vibrations, these testers determine hardness without leaving an indent on hardened materials. They only leave minimal damage on softer metal and work on metal as thin as 0.08”. Use the included test block to determine the right amount of force to apply to your probe. To perform a test, press the diamond tip probe into your material and apply consistent pressure for reliable results. These testers are highly precise and convert measurements between Rockwell, Vickers, and Brinell ratings. Measurements are shown on a backlit digital display, so you can read them even in dark or dimly lit areas. Store up to 2,000 readings with their built-in memory or transfer the data to your PC using the USB port. Small enough to carry, take these testers to your material. Their lithium ion (Li-Ion) battery keeps them running for up to six hours before recharging is required. Energy efficiency requirements restrict sales to the listed areas.
NIST calibrated test blocks are included to help you understand how to properly press the probe to your material for an accurate result. The test blocks can also be used to recalibrate the device. These testers must be calibrated to the specific hardness scale and material being tested. They come pre-calibrated with five combinations: aluminum on the Rockwell B scale, brass on the Rockwell B scale, steel on the Rockwell C and B scales, and steel on the Brinell scale.
