Non-destructive Aluminum Portable Webster Hardness Tester with Digital Display, Range 0-20HW
Technical Data Download: iqualitrol Digital Webster Hardness Tester DW-20
Brief Introduction:
iqualitrol DW-20 series aluminum Webster hardness tester is also called clamp type hardness tester, They are divided into DW-20, DW-20A, DW-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 work-piece on site and meet the needs of quality control and qualified rate, 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.
Models and Applications:
► DW-20 Webster hardness tester is mainly used for inspection of aluminum alloy, tubes and plate,
► DW-20A type can be used to inspect industrial aluminum extrusions, plates or parts which of the thickness upper limit to 13 mm,
► DW-20B type for testing small aluminum profiles or aluminum profiles pipes which of the inner diameter is greater than 6 mm.
Features:
1,Small portable instrument, small size, light weight, one-handed operation, can quickly measure the hardness of aluminum alloy;
2,Test process without sampling, can be non-destructive testing of material hardness;
3,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;
4,There is no strict limit on the shape of the work-piece to be measured, suitable for the detection of different shapes of aluminum;
5,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 can not read the value;
6,The instrument can preset the hardness range, the quality of the work-piece to be tested, the hardness of the work-piece parts range control, improve the measurement efficiency.
