SW-20 Digital Hardness Tester Portable Hardness Tester
SW-20 Aluminum Alloy Webster Hardness Tester (also known as the
clamp-type hardness tester) is a lightweight, on-site instrument
that can quickly test the hardness of aluminum alloys. The test is
rapid, simple, and one card can be used. The hardness value can be
read directly. It conforms to the China Nonferrous Metals Standard
YS/T420 and American Standard ASTM B647. It is one of the two
instruments recommended by the standard YS/T420.
Main functions and features:
1. The Webster hardness tester is suitable for testing profiles,
tubes and plates. It is particularly suitable for the rapid and
non-destructive inspection of product hardness at the production
site, sales site or construction site.
2. Quick and direct digital display hardness tester.
3. Webster hardness value can be converted into commonly used
Vickers, Rockwell, Brinell hardness and tensile strength values.
Main purpose and application:
1. Determine whether the workpiece heat treatment, check the heat
treatment effect
2. Determine whether the workpiece is not processed by the
appropriate alloy
3. Test inconvenience to the laboratory's long, heavy workpiece or
assembly
4. For production inspection, acceptance inspection and quality
supervision and inspection
5. Mainly used to measure the hardness of aluminum alloy (1100~7075
series)
Technical parameters:
1. Range: 0-20HW
2. Accuracy: 0.5HW
3. Display resolution: 0.1HW
4. Measuring range: equivalent to Rockwell hardness 20 ~ 110HRE.
