Rohmann Elotest B300

Multi-Channel Multi-Media Eddy-Current Test Instrument with active Color TFT-Display

Having set new standards with the ELOTEST B1, its successor the ELOTEST B300, now opens a new dimension of user-friendly operation and future-oriented features.

The ELOTEST B300 combines the B1´s renowned eddy-current technology with state-of-the-art features supported by a modern PC-system and software.

With these built-in features you can operate this powerful instrument with or without an external computer. With additional software (ScanAlyzer etc.) you can expand the already outstanding capabilities of the B300 even more.

The new ergonomically designed solid housing, offers you not only a generously dimensioned user interface (display and keypad) during testing, but also maximum protection and minimum size when the instrument is stored or carried.
