Overview

The Japanese Sanfeng HH-411 Leeb hardness tester is a portable hardness tester that is compact, lightweight, and easy to operate. With just the press of a button, anyone can perform hardness measurement operations, making the HH-411 Leeb hardness tester widely used for measuring various components in the workshop.

Product Details

The HH-411 Leeb hardness tester automatically detects the positioning direction of the impact body and automatically corrects it to ensure maximum accuracy. Hardness measurement can be performed on small surfaces with just a small area (standard D type: ø 22mm, available as DL type: ø 4mm). Therefore, the HH-411 Leeb hardness tester can be used to measure specimens of various shapes, such as around grooves and gear teeth.

Equipped with data storage function

It can store 1800 measurement results and can be used for patrol inspection in the workshop. Hardness standards can be selected according to individual needs, based on the HL hardness value (L value: according to ASTM A956), to convert Vickers, Brinell, Rockwell C, Rockwell B, and Shore hardness values as well as tensile strength. The conversion can be performed after testing or using the hardness value display function in conversion mode.

Powerful operability

The basic operation is to press the impact body onto the surface of the sample, and then press the button like using a ballpoint pen, so the operation is simple and easy for anyone.
