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.
