W-20 Webster Hardness Tester

Features W-20Series Webster Hardness Tester is a portable instrument which can perform on-site hardness testing on soft materials. By a quick and easy test, the hardness value can be read out directly with a simple clamp, in accordance with American Standard ASTM B647. A test can be completed by one press. ModelW-20 equivalent to US Model B Tester Very fast, very simple and very portable, small indentation. Suitable for testing the hardness of aluminium profiles, tubings, sheets and other shapes. Used for testing the with long or heavy workpieces or assemblies inconvenient to be sent to the labs. Used to check the result of heat treatment and determine if the mechanical performace of the workpiece is acceptable. The Webster hardness value can be converted into the common-used Vickers, Rockwell and Brinell hardness value. Different models available for testing aluminum alloys,brass, copper alloy and copper. Application Used to ascertain if the work piece has been heat-treated and check the effect of heat treatment. Used to ascertain if the work piece is made and processed by improper alloys. Used for testing the work pieces with overlength, overweight or assemblies. Used for production inspection, acceptance inspection and quality monitoring and inspection Main Technical Parameters Measuring Scope: 0-20HW Accuracy: 0.5HW Weight: 0.5kg Standard Package 1 Tester 1 Standard hardness block 1 Spare indenter 1 calibration wrench 1 Small screwdriver 1 Carrying case Optional Accessaries Indenter Standard hardness block Spare dial head Calibration wrench Dial Glass Model Selection No.TypeApplicationTesting RangeSpecimen Size/mm1W-20Aluminum alloy25-110 HRE58-131 HVThickness 0.4-6 Inner diameter>102W-20aThickness 0.4-13Inner diameter>103W-20bThickness 0.4-8Inner diameter>64W-B75 Brass in hard or half hard state, super-hard aluminum alloy 63-105 HRFThickness 0.4-6Inner diameter>105W-B75bThickness 0.4-8Inner diameter>66W-BB75Soft brass, pure copper 18-100 HREThickness 0.4-6Inner diameter>107W-BB75bThickness 0.4-8Inner diameter>68W-B92Cold-rolled steel sheet, stainless steel 50-92 HRBThickness 0.4-6Inner diameter>10
