CISAM-Ernst AT130 / AT250 – bench-top Rockwell hardness testers
Applications
For Rockwell, Super Rockwell and Brinell hardness testing in production and in the laboratory. The spring-loaded load system eliminates the influence of material deformation (bending) and provides a 2 s test cycle with a single lever movement. AT130 – basic model with digital display and RS232; AT250 – with colour touchscreen, memory for 400 files and extended interfaces.
Key features
- Patented Ernst spring load system – insensitive to sinking-in and bending
- 2 s test cycle, one lever movement per test
- Manual load application with automatic preload
- Resistant to dust and vibration (for production conditions)
- 4 stand configurations (NX, TX, CAR, MUR); MOD DR and MOD DSR versions
- AT250: memory for 400 files × 2,500 results, USB printer / USB export
