Portable hardness tester


Light force wireless portable hardness tester e-computest is a light force (5kgf) electronic hardness tester, which operates according to the Rockwell principle and allows the hardness of the entire range of ferrous and non-ferrous metals to be measured without changing the indenter. Simply select the desired scale and place the base of the instrument on the surface to be tested, preparing the test area accordingly.

The measurement is obtained by exerting a manual pressure of 5 kgf with immediate display of the detected hardness value. The e-computest portable hardness tester can operate in different positions and is equipped with various support bases, easily interchangeable to adapt to the different shapes of the samples to be measured.

In the new version e-computest uses a tablet suitable for the industrial environment. The Android application offers the possibility of detecting, managing, sharing, archiving and printing data in a simple and immediate way. In addition, e-computest can be used with a stand, specifically designed to perform tests of all those pieces where support is required and of small samples.
