Rilevatore di difetti UD-3701

Il rilevatore di difetti ad ultrasuoni NOVOTEST UD3701 è progettato per rilevare difetti, quali discontinuità ed eterogeneità negli oggetti, qualità dei giunti saldati, per misurare la profondità e la posizione di difetti, misure di spessore, misure di velocità e attenuazione di onde ultrasoniche per diversi materiali.

Descrizione

Lo strumento UD3701 dispone di un ampio display touchscreen da 7 pollici e involucro metallico potente, leggero, portatile ed ergonomico, ed è la scelta migliore per i test ad ultrasuoni esperti. Il rilevatore di difetti ad ultrasuoni NOVOTEST UD3701 consente all’utente di misurare lo spessore dei prodotti con elevata accuratezza, il segnale può essere visualizzato sotto forma di scansione A e scansione B e ha tutte le caratteristiche della documentazione di prova completa.
