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:
1, DW-20 Webster hardness tester is mainly used for inspection of
aluminum alloy, tubes and plate,
2, DW-20A type can be used to inspect industrial aluminum
extrusions, plates or parts which of the thickness upper limit to
13 mm,
3, 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.
