SENSOPHONE AED404-USB

Four-channel acoustic-emission device

The SENSOPHONE AED404-USB 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. It allows to set-up the simplest and absolutely less expensive multichannel AE diagnostic system: up to four AE sensors with built-in preamplifier and fixing magnet and integrated 2 m sensor cable, the AED404-USB itself, and a USB cable for connecting to the notebook.
