ERNST is a company with over 50 years’ experience in the research, design and production of high quality hardness testers.
Active in the international market with an extensive range of hardness testers, it gathers information and requests from a demanding and diversified market, in order to continue to be at the forefront of the production of machines for controlling, measuring and testing materials.
ERNST patents are the story and the future of the company, a company that is constantly researching new technological solutions to the still unsolved problems in metal hardness testing.
The range of ERNST hardness testers includes:
- light and heavy load portable hardness testers, suitable for testing large specimens, irregular shapes, and awkward test points that bench testers cannot reach
- bench hardness testers for Rockwell and Brinell testing with direct reading in many other hardness scales
- automatic hardness testers for high volume testing and completely in-line testing operations.
All ERNST hardness testers operate according to a variant of the Rockwell method that permits accurate and reliable results also in the presence of deflection of the test part.
The series ESATEST hardness testers is based on a new testing method based on the measurement of the electrical resistivity and patented by ERNST. This method allows determining in a rapid way the material hardness in awkward test points, such as interiors, irregular shapes, gear evolvents.
The experience and the specialisation, the possibility to offer customized solutions, the extensive range of hardness testers make ERNST a worldwide leader in the production of testing instruments.
The range of Ernst portable hardness testers include:
COMPUTEST SC Portable hardness testers with direct reading of test results on LCD backlit display. Seven or more hardness scales available. Static testing on flat and cylindrical surfaces and on different metals.
Test load 5 kp. Output RS232.
DYNATEST SC Portable hardness tester similar to COMPUTEST SC, but with heavy load (more than 100 kp).
Four or more hardness scales available.
Unique of its kind, this portable tester allows the accuracy of a bench hardness tester thanks to the heavy load.
Ouput RS232.
HANDY Portable hardness testers ESATEST-series
Portable execution of the MTR model. Weight of the instrument 1.5 kg
Output RS232.
STE A / STE B Dynamic or static-dynamic portable hardness testers working with calibrated pins. Test load 1580 kp. Test results in Brinell scale and tensile strength. In compliance with the Brinell 30 D² standards.
