Ernst is officially authorised to provide HANDY ESATEST X with an ACCREDIA (UKAS equivalent) calibration certificate, in accordance with DIN 50158-2.

The Portable hardness tester Handy Esatest (DIN 50158) has been designed to solve some still unsolved problems in hardness testing. The innovative ESATEST® principle patented by Ernst, works based on the hardness determination through electrical resistance and allows to test in difficult and inaccessible points, unobtainable with other hardness testers. With a simple indentation it is possible to get all values corresponding to the different forces up to the maximum force applied thus allowing getting an indicative evaluation of the heat treatment characteristics. The measurement is not influenced by deflection or bending of the specimen. Handy Esatest X permits hardness testing of all types of metal without changing the penetrator.
