Webster Hardness Tester MW-20

Description

Function & application

Confirm the workpiece is heat-treated or not,
Whether the workpiece is made of improper alloy;
Testing over-long or over-weight workpiece;
Project acceptance of aluminum factories
Do project acceptance in companies of windows, door and curtain wall.


MW series webster hardness tester can be classified into four different types according to alloy content and hardness range. Except for MW-B92, each one has three kinds according to size of material.User should choose the right type to measure in case that you may damage the instrument.

Working Principle
MW series Webster hardness tester adopts indentation principle. Under pressure, the indentation is inversely proportional to the material hardness. HW is short for hardness of Webster, when the value is 16, it means the hardness is 16HW. The value can be read on the dial and can be changed into HV, HR. If the sample hardness is out of range, the needle will point at 20, if the range is too low, the needle will not move and it will stay at 0.

Working Conditions
The tester should be used in environment of clean, no vibration and no corrosive medium.

Instrument Features
No corrosion and keep precision after we have put them in salty water(5%) for 4 hour. After 100 times 0.5meters falling test, the pointer does not deflect.Thus to ensure the quality of the instrument.
Small portable instrument, small size, light weight, one-handed operation, can quickly measure the hardness of aluminum alloy;
Test process without sampling, can be non-destructive testing of material hardness
Easy to learn, no high-skill skills of the operation requirements, the human operation on the measurement results less impact, very suitable for the production site for rapid hardness testing of materials;
There is no strict limit on the shape of the workpiece to be measured, suitable for the detection of different shapes of aluminum;
Equipped with calibration sets to solve the problem due to multiple full scale calibration if there is a calibration error;
Detection and display separated, to avoid blocking display so that user can not read the value.
