Product Highlights

HH-411 Display Only, Display unit UD-410

HH-411 is a compact portable hardness tester that is user-friendly. A single touch of a button performs the non-destructive impact hardness test so it's extremely easy to test workpieces on site.

User-friendly

To make a hardness test, just press the button on the impactor while holding it against the workpiece surface. It is easy and user-friendly.

A choice of impactor

• D type: Standard, general purpose type.
• DC type: For inner walls of pipes.
• D+15 type: For bearings and gears.
• DL type: For narrow features such as small gear teeth and welded corners.

Equipped with data storage function

A maximum 1800 data entries of hardness test results can be stored. This function is very useful for routine tests at work sites.

Hardness testing on narrow surfaces is possible

Only a small surface area is needed for testing hardness with the HH-411. (A small o22mm for the standard type D impactor, and a minute o4mm for the optional type DL impactor.) This feature makes the HH-411 extremely useful for testing the hardness of surfaces such as structural elements, gear teeth, etc.

Equipped with auto angle compensation function

Impact-type hardness measurements are normally affected by gravity, depending on the angle at which the impactor is held, but the HH-411 is equipped with the latest measuring technology that automatically recognizes impactor orientation and compensates for this effect so maximum accuracy is realized in every measurement.

Unit of hardness is selectable for various purposes

The HH-411 produces HL hardness scale results (L hardness: conforming to ASTM A 956), automatically converting to Vickers, Brinell, Rockwell C, Rockwell B, Shore and tensile strength, as required during testing.
