MH100 series pocket hardness meters, also known as pen-type hardness tester, based on Leeb hardness measuring principle, quick and easy on-site test the hardness of series metal materials, support free conversion between Richter, Brinell, Rockwell hardness scale and others,integrated compact design, small size, portable, highly integrated, stable and reliable performance, supporting data transfer and print the stored function. 

Widely used in failure analysis of metal processing and manufacturing, special equipment, permanent assembly, inspection and other fields. Particularly suitable for large parts and non-removable part of the site hardness testing. It is professional precision instrument to improve the pass rate of production and cost savings .

 

 

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

 

Working Principle

The energy quotient is quoted in the hardness unit HL and is calculated from comparing the impact and rebound velocities of the impact body. It rebounds faster from harder samples than from softer ones, resulting in a greater energy quotient which is defined as 1000×Vr/ Vi.

HL=1000×Vr/ Vi

Where:

HL— Leeb hardness value

Vr — Rebound velocity of the impact body

       Vi — Impact velocity of the impact body
