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. 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. 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
