MSW-20A MITECH

Overview
MSW-20 series aluminum Webster tester is also called clamp type hardness tester, They are divided into MSW-20, MSW-20a, MSW-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-20 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.

Instrument Features
l Small portable instrument, small size, light weight, one-handed operation, can quickly measure the hardness of aluminum alloy;
l Test process without sampling, can be non-destructive testing of material hardness;
l 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;
l There is no strict limit on the shape of the workpiece to be measured, suitable for the detection of different shapes of aluminum;
l Compared with the traditional clamp hardness tester, the digital display is more convenient to read the value, detection and display function separately, to avoid the technical staff in the field when the display device is blocked and cannot read the value;
