Mitech digital hardness tester MW-B75 easy for use, can test rapidly, and the hardness value can be read out directly
Overview
MW series aluminum Webster tester is also called clamp type hardness tester, They are divided into MW, MW-20a, MW-20b three types, they are light and portable can be hold by one hand, do not need sample when testing, without high skill requirements. It can do fast NDT test of workpiece on site and meet the needs of quality control and qualified rate. It is widely used in production test, acceptance inspection and products quality inspection of aluminum industries and many companies of windows, door and curtain wall, as well as in engineering quality inspection and technical supervision departments. It is a necessary device in raising qualification rate and saving cost.
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.
Technical Parameters
- Measurement Range: 0~20HW
- Accuracy: 0.5HW
- Accurate Measurement Range: 5~18HW
- Hardness Range: 25～110HRE, 58～131HV
- Test material: Aluminum Alloy(1100~7075 Series)

Application
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.

Note: For materials with a thickness less than 0.88mm, the use would meet an "anvil effect". At this time a small trace will appear on the back of the measured material. this "anvil effect" will cause measurement error, the larger the traces, the greater the error; the more soft the material, the thinner the thickness, this error will be greater .The For thinner materials, it is helpful to reduce the error caused by the "anvil effect" by superimposing the two materials with the same material.
