Buehler – Wilson UH4000 Universal Hardness Tester
The completely customizable Wilson UH4000 series offers wide-ranging flexibility to high-volume environments. Controlled by DiaMet software, both the UH4250 and UH4750 models focus on fast and simple operation while maintaining the complexity of features required by expert users. Features include an optional clamping tool for stability, an 8-position turret, laser for precise targeting, and ring light for accurate Brinell measurements. The steel casting ensures durability, reducing service costs and increasing up-time in production environments.
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.
