Brinell hardness tester HBS3000-212

benchtopdigitalEN-ISO 6506

Product Overview
The HBS3000-212 is a digital Brinell hardness tester designed for laboratory and workshop use. It uses a precision stepper-motor closed-loop control system combined with optical measurement to provide accurate test-force application across a wide range of forces. Indentation measurement is performed manually using the micrometer eyepiece. The instrument is suitable for cast iron, steel, nonferrous metals and selected nonmetallic materials and is intended for quality control, inspection and research applications.
