China Measuring Instrument Hardness Detector Hardness Meter

Product DescriptionProductOverview

MH320 portable Leeb hardness tester is based on Leeb hardness measurement principle, it can be quickly and easilyused foron-sitetesting hardnessofmetallicmaterialsandsupportfree conversion betweenLeeb, Brinell, Rockwell hardness and otherscales.It uses 128 x 64 dot matrix LCD screen,rich information,intuitive, stable performanceandintegrated high-speed thermal printer,whichenablesprinting with instant measurement results.It can bewidely 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 theon-site hardness testing. It is to improve production efficiency and pass rateand is aSpecialized Case & Box wise choice to savethe cost of production.

Function & application

lDie cavity of molds

lBearings and other parts

lFailure analysis of pressure vessel, steam generator and other equipment

lHeavy work piece

lThe installed machinery and permanently assembled parts.

lTesting surface of a small hollow space

lRequirements offormal original recordfortest results

lMaterial identification in the warehouse of metallic materials

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

WorkingPrinciple

The energy quotient is quoted in the hardness unit HL and is calculated from comparing the Transmitter impact and rebound velocities of the impact body. It rebounWelding & Soldering Supplies ds faster from harder samples than from softer ones, resulting in a greater energy quotient which is definedBuilding Material Making Machinery as 1000xVr/ Vi.

HL=1000xVr/ Vi

Where:

HL- Leeb hardness value

Vr - Rebound velocity of the impact body

Vi - Impact velocity of the impact body

WorkingConditions

lWorking temperature:-10ºC~+50ºC;

lStorage temperature:-30ºC~+60ºC

lRelative humWashing Equipment idity: ≤90%;

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