Rockwell hardness tester HRS-150B

BrinellVickersbenchtop

Product overview
The HRS-150B digital display, height-adjustable Rockwell hardness tester is an automated precision instrument for hardness testing of medium to large components. Key features include motorised loading/unloading, a 5.6-inch colour touchscreen and a 400 mm maximum specimen height, enabling efficient and repeatable Rockwell measurements and data management.

Product advantages

• Automatic force application and release; supports automatic calculation for 15 Rockwell scales including HRA.
• Integrated dual-core 32-bit ARM processor for on-board data processing and display.
• Dual control: colour resistive touchscreen for parameter setting plus touch buttons to reduce mechanical-wear risks.
• Motor-controlled application, dwell and removal of test force to eliminate manual tester variability.
• Built-in hardness conversion using ASTM E140-12be, ISO 18265:2013 and GB/T 1172 standards for automatic conversions.
• Single-point and multi-point statistical modes; stores 200 single-point records and 100 multi-point records; multi-point mode includes hardness distribution curve analysis and automatic max/min/average calculations.
• Operating system supports 12 languages for international use.
• Fifteen measurement scales can be calibrated independently; built-in printer for result output.
• Pre-test force locking: lead screw locks at 98.07 N (10 kgf) to prevent pre-load overshoot.
