MH180 portable Leeb hardness tester, based on Leeb hardness measuring principle, quick and easy,on-site test the hardness of series metal materials, support free conversion between Leeb, Brinell, Rockwell hardness scale and others,It uses high-contrast segment LCD to display, small size, light,portable, stable and reliable performance.

Widely used in failure analysis of metal processing and manufacturing, special equipment, permanent assembly, inspection and other fields. It can meet the regular hardness testing of industrial production , quality and cheap, which is the first choice for practical and economical models.


Function & Application: 


Die cavity of molds

Bearings and other parts

Failure analysis of pressure vessel, steam generator and other equipment

Heavy work piece

The installed machinery and permanently assembled parts.

Testing surface of a small hollow space

Requirements of formal original record for test results

Material identification in the warehouse of metallic materials

Rapid testing in large range and multi-measuring areas for large-scale work piece




Features:

Surface temperature can’t be overheat, less than 120 ℃.

Surface roughness should not be too large, otherwise it will cause errors. The surface of the work piece must be exposed metallic luster, smoothing and polish, without oil.

The specimens with 2-5kg or thin-walled specimens overhangs should be supported with some object in order to avoid the pecimen deformation ,bending and movement caused by impact , for medium-sizedwork piece ,it shall be placed on a flat and hard surface, the sample must be placed absolutely smoothly, without any shake, for heavy samples more than 5kg, it can be measured directly without any support

 Portable Leeb hardness tester has strict requirements for sample thickness , the minimum thickness shall comply with regulatory .

For work piece with hardened layer on surface,the depth of hardened layer should conform to regulatory.

For lighter parts,please make it tightly coupled with support, two coupled surface must be flat and smooth, the coupling gel should not be too much, the direction of the test shall be perpendicular to the coupling plate; if the work piece is a large plate, pole or bending material, even if the weight and thickness is ok ,it may still cause deformation and instability, resulting in test values error, it should be reinforced or supported at the back of the test points.

Magnetic of work piece should be less than 30 gauss.
