Mitutoyo HH-411 Portable Hardness Tester

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. Alternate impactor options are available below for testing inner walls of pipes, bearings and gears, and for narrow features such as small gear teeth and welded corners. A maximum 1800 data entries of hardness test results can be stored. The hardness tester is equipped with an auto angle compensation function that automatically recognizes the impactor orientation and compensates for this effect so maximum accuracy is realized in each measurement. The hand-held hardness tester HH-411 has the following specifications:

Impactor: impact hammer with integrated detector and carbide-ball tip (type D conforming to ASTM A 956). Alternative impactors are available including DC Detector for inner walls of cylinders, D+15 Detector for concave workpieces such as gears or ball bearings, and DL Detector for narrow gear teeth or welded corners.
