Rohmann Gmbh

ELOTEST \ M6

In 1977, the Rohmann success story began with the portable
rototest and now continues with the new ELOTEST M6. This digital one-hand tester impresses with its excellent signal quality. The new handheld ELOTEST M6 impresses with integrated C-Scan function for array probes and rotor applications. It is the first handheld instrument with harmonic analysis for testing microstructural, hardness and strength changes in metallic materials.

A completely new generation of eddy current tester

With the ELOTEST M6 you hold the most innovative handheld tester in its class in your hands. Whether in a horizontal orientation as a tabletop unit or vertically as a handheld tester – all flexibility in one unit. Whether right- or left-handed – all personal habits of the user are taken into account.
The 7″ touch screen gives you a comprehensive and flexible overview of your test result. With the 3-fold multi-touch, you have your finger on the pulse and the tester can thus be operated in any situation.
Always on hand: reference standards directly on the test instrument. Individually, depending on the test requirement, the reference parts can be exchanged.
