Bench Hardness Tester NR3D
The NR3-D hardness tester by Cisam-Ernst is an excellent choice for measuring hardness based on the Rockwell principle, with standardized preload and load. Available in both standard Rockwell and superficial versions, the NR3-D stands out for its versatility, allowing the testing of a wide range of materials, from the hardest metals to light alloys and even plastic. Its versatility is backed by a wide selection of loads and indenters, ensuring accuracy even for small and medium-sized items.
Key Features
- Rockwell & Superficial Rockwell: Easy interchangeability between standard and superficial versions using the same stand
- Measures in Brinell Points Too: Provides readings on standard HB 30 scales, HB 10, and HB 5 for light alloys and aluminium
- High Durability: The spring-loaded system makes the NR3-D ideal for challenging environments with extreme temperatures, dust, humidity, and vibrations
- Robust and Easy to Use: Perfect for schools and laboratories, thanks to its sturdy structure and ease of use
- Low Investment: An affordable price that ensures a quick return on investment
- Optimal for Composite Materials and Spheres: The absence of the locking pin and presser allows for precise measurements even on small-sized parts
- Brinell Indenters Available: Allows for accurate measurements using Brinell loads and indenters
- Removable Measuring Head: Facilitates faster revisions and calibrations
- Absence of penetrator and penetrator shroud - Allows the measurement of small parts and is ideal for the control of spheres or composite materials
