HH-411 is a rebound type portable hardness tester for metal with a compact body and high operability.

It allows anyone to perform hardness testing easily at the touch of a key, so it can be used widely on various components in the field.

Hardness testing of small surfaces is possible

Only a small surface (standard D type: Ø22mm, separately sold DL type: Ø4mm) area on is required for hardness testing. Therefore the HH-411 can be used for testing of various specimen shapes such as around grooves and gear teeth.

Equipped with a data save function

Up to 1800 hardness test results can be saved, which is useful for patrol tests in the field.

Hardness scale can be selected for your own individual purpose

Based on the hardness HL value (L value: according to ASTM A 956), conversion can be performed to Vickers, Brinell, Rockwell C, Rockwell B, and Shore hardness as well as tensile strength. Conversion can be performed after the test, or hardness value display in the conversion mode is also available.
