SENSOPHONE AED404-STREAMER
Four-channel acoustic-emission device
The SENSOPHONE AED404-STREAMER acoustic-emission device is a modern measuring device for non-destructive diagnostic testing of materials and structures. It is the centre of a full featured four-channel AE diagnostic system in university research laboratories or for field examination of small industrial objects. Compared to all other members of the SENSOPHONE AED4xx family, it has an extra functionality: the AED404-STREAMER can continuously save the original signal of the selected or even all AE channels to an external storage unit.
