Webster Hardness Tester W-20 - ASTM B647/ inner diameter >10mm, , specimen dimension of 0.4-6mm
Webster hardness tester is a portable one-hand operation instrument for on-site soft metal hardness testing. It is used to inspect the result of heat treatment, and to sort the materials in the warehouse.. The Webster hardness tester is very suitable for one-by-one quality inspection of batches in the production line. The hardness value can be read directly on the indicator dial. The testing is done by simply applying pressure to the handle so that the bottom is felt. W-20 requires a specimen dimension of 0.4-6mm for regular type aluminum alloy, pipe, and sheet metal. Inner diameter >10mm. Hardness range 25-110 HRE, 58-131HV.
The W series of portable instruments perform on-site hardness tests on aluminum alloys. The test result is obtained with a simple clamping of the two handles. It is convenient, efficient, and reliable and tests aluminum alloys' mechanical performance in accordance with American standard ASTM B 647. It is ideal for a quick test of hardness on aluminum profiles, tubings, sheets, accessories, and other soft metal, non-destructive on-site 100% final products qualification test. The W series Webster hardness tester can be also used for testing the hardness of copper, brass, and soft steel. The Indenter is Re-engineered with advanced material and new production technology manufactured, higher hardness, long service life, good interchangeability. The Indicator Hand has High strength indicator hand, less likely to be bent by long-term use or misoperation. The Dial Glass has great strength, toughness, uneasy to be broken or scratched. The handle is made of a forged aluminum alloy handle with fine anodized finishing, high resistance to abrasion and stain. Hardness Blocks: Tested by a standard Rockwell hardness tester, the hardness block is attached with a test report. Stabil ty: Stable full-scale point, stable calibration point, indicator never glides. Conversion: Results can be converted to Vickers, Rockwell, and Brinell. It comes complete with the main tester, Standard hardness block, Spare indenter, Calibration wrench, Small screwdriver, Carrying Case, and Dial assembly.
