ERNST is a company with over 50 years’ experience in the research, design and production of high quality metal hardness testers.
Active in the international market with an extensive range of metal 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 sales program of Ernst includes:

Rockwell hardness testers
Brinell hardness testers
Vickers hardness testers
Portable hardness testers
Bench hardness testers
Among all kinds of inspections that are carried out in a workshop testing of hardness is the most diversified.
Testing can be made at 3000 kp (29430N) or with some hundreds grams; in laboratories, testing is made even with few grams.
It is possible to test the hardness of heavy castings as well as of pins for horology, from the hardest sintered materials to the softest alloys.
There are so many methods and hardness scales to be used that even those who have a considerable workshop experience can get confused when facing such problems.

Ernst manufactures and distributes different kinds of metal hardness testers, to meet the various testing requirements.

It is possible to move the work piece under the tester as well as the tester over the work piece. The first case concerns bench hardness testers, that allow holding and clamping of the part during testing; bench hardness testers are suitable for testing of small and medium parts.
The second case concerns portable hardness testers that can be clamped to the work piece or simply placed on large and irregular parts.

Testing on particularly difficult parts should be evaluated from time to time
