Mitech Integrated Hardness Tester MH100 , portable , precison
different from Ultrasonic Hardness Tester
MH100 Portable hardness tester Overview
Compact and integrated. The impact device and the main body
integrated together.
Wide measuring range. Based on the principle of Leeb hardness
testing theory. It can measure the Leeb hardness of all metallic
materials.
Large screen LCD, showing all functions and parameters. With EL
background light.
Test at any angle, even upside down.
Direct display of hardness scales HRB, HRC, HRA, HV, HB, HS, HL.
Large memory could store 100 groups (Relative to average times 32～1
) information including single measured value, mean value, impact
direction, impact times, material and hardness scale etc.
Battery information showing the rest capacity of the battery and
the charge status.
User calibration function.
Software to connect to PC via USB port.
Li-Ion rechargeable battery as the power source. Charge circuit
integrated inside the instrument. Continuous working period of no
less than 200 hours (EL off and no printing).
Auto power off to save energy.
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
Operating Method and Attentions
Start-Up
Press the power key to start up the instrument. The instrument then
comes into working mode.
Loading
Pushing the loading-tube downwards until contact is felt. Then
allow it to slowly return to the starting position or using other
method locking the impact body.
Localization
Press the impact device supporting ring firmly on the surface of
the sample, the impact direction should be vertical to the testing
surface.
Testing
Main 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
Material identification in the warehouse of metallic materials
Rapid testing in large range and multi-measuring areas for
large-scale work piece
