Wilson® UH4000 Universal Hardness Tester

UH4000 Universal Hardness Tester

Automated Hardness Testing System

The Wilson UH4000 Universal Hardness Tester series, tailored for high-volume applications from innovative labs to the production floor, is offered in three configurations: the UH4750, UH4250, and the Auto UH4250 with motorized XY stage. Designed to execute various hardness scales within a single machine, typically for higher loads (>5kgf), these testers encompass all comprehensive Vickers, Knoop, Rockwell, and Brinell scales. Adhering to ISO 6506, 6507, 6508, and 4545, as well as ASTM E18, E10 & E92 standards, the UH4000 series ensures complete hardness testing capabilities. Moreover, it accommodates plastics and carbon testing in line with ISO2039 and DIN51917.
