Bench hardness testers

<body> <h1>Bench hardness testers</h1> <p>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. </p> 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. The range of bench hardness testers: NR3 DR / NR3 DSR Rugged and easy-to-use Rockwell / Superficial Rockwell bench hardness testers, with standardized preload and load. Test loads for Brinell testing. Output RS232 AT130 DR / AT130 DSR Bench hardness testers for Rockwell / Superficial Rockwell testing. Standardized preload and test loads. Test loads for Brinell testing. Four different stands available. Output RS232 AT200 DR / AT200 DSR Bench hardness testers, similar to AT130, with digital readout through microprocessor. Swift testing, data printing, statistics, tolerances, etc. Eight or more hardness scales available. Four test stands available. Test loads for Brinell testing. Output RS 232 and CENTRONICS. MTR Bench hardness tester ESATEST-series ESATEST-series makes use of a new testing principle that allows testing of odd shaped parts, difficult test points, as grooves, holes, involutes. With one test only, it is possible to display the hardness values at different loads. This is particularly helpful when testing of surface treated areas to learn immediately the case depth. Test results are automatically shown on a LCD backlit display. The electronics permits further different functions. MTR is the motorized version of the ESATEST-series. Output RS232 and CENTRONICS. TWIN Bench hardness testers for testing of Rockwell and Superficial Rockwell hardness. Test head displacement, load change and load application are automatic. 45 mm penetrator’s stroke Insensitive to any deflection of the test piece. Possibility of removing the elevating screw assembly for in-line applications. The electronics permits further different functions. Output CENTRONICS BRE-AUT Automatic hardness tester for Brinell testing with variable loads from 500 to 3000 kp. Suitable for custom in-line applications. Output RS232 and CENTRONICS. </body>
