The Mitutoyo HH-411 is a user-friendly rebound-type portable hardness tester for metal with a compact body and high operability. The HH-411 has excellent operability that performs hardness tests with the touch of a key and a compact body allows users to measure hardness in the field. This instrument is best suited for on-site hardness tests such as large molds, railroad tracks, and welded spots in structures. The Mitutoyo HH-411 Hardness Tester features a selectable unit of hardness, automatically converting HL hardness scale results to Vickers, Brinell, Rockwell C, Rockwell B, Shore, and tensile strength as required during testing. This function, along with generous storage capabilities and easy portability makes the HH-411 ideal for testing in the field.

• Single button touch performs a non-destructive impact hardness test for easy on-site workpiece testing
• The data storage function stores a maximum of 1800 data entries for performing routine tests at work sites
• Auto angle compensation automatically recognizes impactor orientation and compensates so maximum accuracy is achieved in every measurement
• ASTM standard Including the display unit, D-type impactor (810-287-10), and carbide ball (19BAA457)
