Benchtop Rockwell Hardness Testers
Bring material right to your bench to measure its hardness. These testers use a carbide indenter to take accurate Rockwell hardness readings every time. They come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. With a durable metal body, these testers stand up to many environments, from heat treat facilities to workshops to inspection labs. They show readings on a dial—no need to hook them up to a power source.
These testers come with indenters for different scales, three anvils, four test blocks, and a case to store accessories. Use the included cover to shield them from dust when they’re not in use.

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.
Durometer Hardness Testers
Measure the hardness of flat materials, such as plastic, rubber, and laminate.
Style 3 testers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Digital Durometer Hardness Testers
Measure the hardness of flat materials with a digital display.
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.

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.

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 Calibration Test Blocks
Check your hardness tester for accuracy against a block with a known hardness rating. Each block is tested according to ASTM E10, which checks the hardness at five locations along the block. They include a certificate that lists the block’s actual hardness, as well as each of the five measurements taken during the test. Blocks also include a NIST-traceable certificate that states they’ve passed a test for accuracy.
Each block is marked with their Brinell hardness rating and a serial number.
