Universal Hardness Tester: 马来西亚的首选 Eco Instrument

详情

This is a 3-in-1 closed-loop hardness tester that combines Brinell, Rockwell, and Vickers methods without requiring interchangeable weights.

Core Advantages:

Load Cell Technology: Uses a closed-loop load cell system (no physical weights), enabling automatic force correction and high accuracy.
8" Touchscreen: Modern UI for operation, data storage (export to Excel via USB), and password protection.

Wide Test Force Range: Supports 10 different Vickers forces (5–120 kgf), 10 Brinell forces, and standard Rockwell preloads + main loads.

Automatic Features: Hardness conversion (GB/ASTM), Rockwell curvature radius correction, and force compensation.
