Aluminum Webster tester MW-B92

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.

Aluminum outer material

Doors and windows curtain wall, decoration works

Tourism, sports, stationery aluminum processing

Aluminum tubes, aluminum, aluminum, aluminum rods and other aluminum products production and processing

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.

Sample surface should be clean and clean without oil, the surface of the dirt, especially fine sand will greatly affect the measurement accuracy;

Sample surface coating will seriously affect the measurement accuracy, with sandpaper or solvent to remove the coating after the hardness measurement;

The instrument should be used in environments with strong vibrations, damp and corrosive gases;

This series of products according to the different thickness of the four models available for users to choose, different models have different display and measurement range.User according to the shape size and thickness of the sample to select the appropriate The instrument is measured.

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.
