SENSOPHONE AED404-USB

SENSOPHONE AED404-USB and AED404-USB Light

Four-channel acoustic-emission devices

The SENSOPHONE AED404-USB and AED404-USB Light acoustic-emission devices are modern measuring devices for non-destructive diagnostic testing of materials and structures. They are the centre of a four-channel AE diagnostic system in university research laboratories or for field examination of small industrial objects. They allow to set-up the simplest and absolutely less expensive multichannel AE diagnostic system: the AED404-USB or AED404-USB Light itself, up to four AE sensors with built-in preamplifier, fixing magnet and integrated 2 m sensor cable, and a USB cable for connecting to the notebook.
