MBRV-250A Intelligent Automatic Universal Hardness Tester

Product Feature：

• Three testing methods: Brinell, Vickers, and Rockwell.
• Brinell test force range: 5 kgf — 250 kgf.
• Vickers test force range: 3 kgf — 120 kgf.
• Automatically applies initial test force and main test force.
• 8- inch touch screen for convenient operation.
• The test stage can be automatically lifted and also be manuallyfine-tuned. It is equipped with an anti — collision detection device and a Z — axis retraction system.
• Closed loop system with loading cell, equipped with a fully automatic high — precision sensor and a closed-loop feedback control system.
• An ultra — high — precision X/Y auto stage with a repeat positioning accuracy of 3 microns and a maximum travel of up to 200mm (optional).
• Objective magnification: 2.5X, 5X (10X, 20X optional).

Φ2.5 mm, Φ5 mm Brinell ball indenter (Φ1 mm, Φ10 mm are optional).

• Brinell and Vickers tests can be automatically positioned to themeasurement and observation positions.
• 5 — megapixel industrial camera.
• Supports hardness value conversion between multiple scales.
• Hardness measurement software supports automatic/manual measurement, report, export, printing, and data statistics.
• Automatically calculates the uncertainty of the hardness value(optional).
• Automatically generates documents required for CNAS review(optional).
• Executive standards: GB/T230, GB/T231, GB/T4340, JJG144,GB/T18449, ISO 6508, ASTM E 10, ASTM E92, ASTM E18, ASTM ,E384, ASTM E103.

Product Application：

• Materials research:

It is used to evaluate the hardness characteristics of materials and provide data support for material selection, design, and development.

• Production quality control:

During the manufacturing process, it is used to detect whether the hardness of products meets the standards to ensure product quality.

• Failure analysis:

When equipment or parts fail, by analyzing the changes in their hardness, the causes and mechanisms of the failure can be inferred.
