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.
Testers for Shore M durometers take accurate readings on materials as thin as 0.05". Use them to take measurements of areas that are too small for durometer readings with a Shore A scale tester.
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.

O-Ring Durometer Hardness Testers
Test the hardness of thin and irregularly shaped plastic, rubber, and laminate parts, such as O-rings. These testers can be used on products where the surface area is too small for accurate durometer readings with a standard Shore A tester, such as the rounded surface of O-rings. They include O-ring fixtures that hold five standard-sized O-rings in place during testing. These testers are also capable of measuring materials as thin as 0.05″, about the thickness of a credit card. On the display, they’ll show the highest reading until they’re reset. They include a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.
Use the included test blocks to practice taking accurate measurements at the right pressure against your workpiece. Send your measurement data directly to your PC using the USB port.

Brinell Hardness Testers
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.
Ball Indenters for Brinell Hardness Tests
A key component of Brinell hardness testers, these ball indenters are hard enough to make impressions on most metal. Made of carbide, they won’t deform as they press into hard material. Shallow indentations mean a material is hard and deep indentations show that it is soft. Use the diameter of the indentations created by these balls as part of the calculation to find your material’s hardness rating. These ball indenters meet ISO 6506 and ASTM E10 standards for Brinell hardness testing. The shank diameter is a standard size for bench-top Brinell hardness testers.
2.5 mm diameter ball indenters are a good choice when testing material with limited space for measuring or material that is thin and may fracture under heavy loads. They make less contact when indenting your material surface than larger diameter indenters.
10 mm diameter ball indenters are the most commonly used and work well for testing soft material that might deform under heavy loads. They have a large contact area when indenting your material surface, so they distribute the applied load over a larger surface area than smaller diameter indenters. This means there is less stress and pressure at the indentation site.
For technical drawings and 3-D models, click on a part number.
Scratch-Resistance Testers
Determine the relative hardness of resins, film, lacquer, and paint by testing their resistance to scratches by graphite pencils. The pencils are calibrated to specific lead grades for hardness. The lowest hardness value of the pencil that mars the material is the material’s relative hardness. Flatten the tip of the pencil lead with the included 400 grit sandpaper, then insert the pencil into the tester. As you push the tester over your material, the pencil is dragged across the surface at a constant pressure. These testers are often used in the development of synthetic resins. They meet ASTM D3363 for testing the hardness of coatings.
