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.
 
Hardness testing on narrow surfaces is possible
Only a small surface area is needed for testing hardness
with the HH-411. (A small ø22mm for the standard type
D impactor)
 
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.
 
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.
