Automatic Hardness Tester AT350
The AT350 hardness tester represents the cutting edge in hardness measurement based on the Rockwell principle. Automated and reliable, this instrument operates in accordance with EN, DIN, ISO, and ASTM standards, providing accurate results across a wide range of materials. Ideal for testing large parts and for Jominy testing, the AT350 simplifies processes with its motorised stand, adapting easily to different testing conditions.
Key Features
- Rockwell principle - Rapidity of test
- Automatic functioning - Insertion into production line
- The spring loading system, designed by Ernst, ensures tests are insensitive to material deflection or bending during the test
- The spring load system, designed by Ernst, ensures the test speed is 5 times higher than common systems with load cells
- The spring loading system, designed by Ernst, ensures precise and reliable testing in accordance with international standards
Manufacturer
Ernst
Ernst have been driving the research and innovation in hardness testing for over 60 years. Ernst produce portable, automatic and bench-top hardness testers, covering all hardness testing requirements, together with products that extend their functionalities such as indentation readers and case depth analysers.
Overview
The AT350's ability to automatically apply preload during measurements reduces the required time and minimises errors, allowing automatic batch control without the need for an operator. With Cisam-Ernst's patented spring load system, the AT350 ensures precision and reliability even in the harshest environments, withstanding extreme temperatures, dust, humidity, and vibrations.
Thanks to Cisam-Ernst's commitment to precision and reliability, the AT350 is designed to withstand intensive use and the test of time, offering robust instruments that can maintain optimal performance over the long term.
