acoustic-emission device

The SENSOPHONE AED404 acoustic-emission device is a modern measuring instrument for non-destructive diagnostic testing of materials and structures. When it is alone, it can be used as the centre of a full featured four-channel AE diagnostic system in university research laboratories or for field examination of small industrial objects. It is also excellent for continuous monitoring applications. When the application needs more AE measuring channels, it is possible to connect it to additional similar AED404 or AED416 devices to build a multichannel system up to 128 AE channels.
