Product Overview

     MH320 portable Leeb hardness tester is based on Leeb hardness measurement principle, it can be quickly and easily used for on-site testing hardness of metallic materials and support free conversion between Leeb, Brinell, Rockwell hardness and other scales. It uses 128 × 64 dot matrix LCD screen, rich information, intuitive, stable performance and integrated high-speed thermal printer, which enables printing with instant measurement results.It can be widely used in metal processing and manufacturing, special equipment, permanent component failure analysis, inspection and other fields. It is particularly suitable for large parts and non-removable part of the on-site hardness testing. It is to improve production efficiency and pass rate and is a wise choice to save the cost of production.

Function & application

l Die cavity of molds

l Bearings and other parts

l Failure analysis of pressure vessel, steam generator and other equipment

l Heavy work piece

l The installed machinery and permanently assembled parts.

l Testing surface of a small hollow space

l Requirements of formal original record for test results

l 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

Working Conditions

l Working temperature: -10ºC~+50ºC;

l Storage temperature:-30ºC~+60ºC

l Relative humidity: ≤90%;

The surrounding environment should avoid of vibration, strong magnetic field, corrosive medium and heavy dust.
