Product Overview
 MH600 portable Leeb hardness tester, intelligent design can be quickly and easily for on-site testing of metal hardness. IP65 protection, can effectively prevent oil, dust and other corrosion in harsh field environments; with color LCD display, it can also display clear testing results in dim light and strong sunlight environment , which greatly enhance the visual experience; specil multi- point calibration function for convert curve to reduce errors;it can automatically identify the measuring direction when testing, automatically alarm when out of range, to meet the inspection requirements with high precision and multi-angle material collected and support free Conversion between hardness scale; low power consumption design by two AA batteries, support multiple languages. It is widely used in metal processing and manufacturing, special equipment or permanent component failure analysis in service, inspection and other fields. Particularly suitable for large non-removable part of the site hardness testing. It is necessary professional precision instrument to improve the pass rate of production and cost savings .
 
Function & application

 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 basic principle is to use an impact body of certain weight impacts against the testing surface under certain test force, then measure the impacting velocity and the rebounding velocity of the impact body respectively when the spherically test tip is located 1mm above the testing surface.
The calculation formula is as follows:
HL=1000×VB/ VA
Where:
             HL—— Leeb hardness value
             VB—— Rebounding velocity of the impact body
             VA—— Impacting velocity of the impact body


Working Conditions,

l Working temperature：-10℃～＋50℃；
l Storage temperature：-30℃～＋60℃
l Relative humidity: ≤90％；
The surrounding environment should avoid of vibration, strong magnetic field, co
 
Instrument Features
Based on the principle of Leeb hardness testing principle. It can measure the Leeb hardness of all metallic materials.
One main unit can match to 6 impact devices Automatically identify the type without calibration
Automatically identify the state of impact devices(connect,disconnect,error ,etc.).
Automatically identify the direction of impact devices (except G),360° comprehensive free measurement

• 320 × 240 TFT LCD screen. information-rich, intuitive, clear display, adjustable brightness, easy to use in dimly lit environments and intense sunlight.

Basic (single-point) calibration and multi-point calibration function for convert curve,to reduce the test error.Hardness scales can be converted to HL,HRB, HRC,HRA, HV,HS,
Built-in Leeb hardness conversion function to converse HLD to HLC,HLG,HLDL,HLD+15,which is convenient for calibration and value conversion.
Preset up and low limit of hardness value , it will alarm automatically if out of range alarm, convenient for batch testings.
Chinese-English converting, menu operation, easy and convenient.
It can store 500 groups (impact times 32 ~ 1) hardness values, each data includes single testing value, average value,  measurement date / time, impact direction, frequency, material, hardness and other information.
Two ordinary AA batteries, it can work for not less than 100 hours; automatic screen standby , automatic sleep, automatic shutdown and other power-saving features.
USB interface can do transmission measurements, value storage management, value statistical analysis ,printing the value report and batch setting the instrument parameters through the PC data-pro software, to meet the higher demand for quality  assurance and management.
ABS plastic seal design, IP65 protection, which can effectively prevent oil, dust and other corrosion of harsh environments
