W-B92 Webster Hardness Tester

W-B92 Webster Hardness Tester

W-B92 series Webster hardness tester for stainless steel can quickly test the hardness of stainless steel on site. It is convenient to operate,and as long as clamping the test can be finished. The hardness value can be read directly with high efficiency and reliability. 

The Webster Hardness Tester is the first choice instrument for testing the mechanical property of stainless steel plate and strip. 

The Webster Hardness Tester is used for quick testing of austenitic stainless steel and mild steel plate and strip, especially for quick and nondestructive qualification test of batches products one by one on production field, sales site and construction site.
