Bench Hardness Tester AT250
In the realm of materials engineering, Rockwell hardness testers are essential instruments for measuring material hardness. Cisam-Ernst, with its AT250 D model, embodies the evolution of this tradition, offering a cutting-edge solution that combines the precision and speed of traditional Rockwell hardness testers with electronic innovation for test data processing.
Key Features
- Test Speed: The Rockwell principle allows tests to be conducted in just 2 seconds, significantly improving productivity
- Spring-Loaded System: Provides reliable tests that comply with international standards, ensuring measurements are insensitive to material indentation and bending
- Versatility and Precision: Available in both standard and superficial Rockwell versions, the AT250 D conducts precise tests on various materials, adhering to UNI, ISO, DIN, and ASTM standards
- Durability and Adaptability: Resistant to harsh environments, thanks to the spring-loaded system, it maintains performance even under extreme conditions of temperature, dust, and humidity
- Advanced Communication Technology: With a wide range of interfaces, the AT250 D enables easy sharing of measurement data, aligning with Industry 4.0 principles
- Rockwell principle - Test speed: cycle time 2"
- Spring loading system ensures tests are insensitive to material deflection or bending during the test
- The spring-loaded system ensures compliance with international standards
- One lever movement = 1 test - Increased productivity
- Wide choice of interfaces - Sharing of measurement data (Industry 4.0)
