M-9MHardness Testing MachinesStart quality control from the material — Mitutoyo's hardness testing machines can handle itMitutoyo operates a policy of continuous improvement that aims to provide the customer with the benet of the latest technological advances.Therefore the company reserves the right to change any or all aspects of any product specication without notice.HARDMATIC HH-411SERIES 810 — Rebound Type Portable Hardness Tester SPECIFICATIONS•Excellent operability that performs hardness tests with the touch of a key and a compact body allows users to measure hardness at any elds. This instrument is best suited for on-site hardness tests such as large molds, railroad track, and welded spots in structures. Order No.810-299 (JIS), 810-298 (ASTM)Model HH-411DetectorImpact hammer with integrated detector and carbide-ball tip (D type: conforming to ASTM A 956)Display unit7-segment LCDHardness display rangeLeeb hardness: 1 to 999HLDisplay range(This display range varies depending on the conversion table used.)
