Selain fungsi-fungsi tradisional, detektor cacat memiliki masukan dari enkoder 2-sumbu, yang memungkinkan pengguna untuk menghubungkan berbagai scanner untuk membangun C-, B- dan scan lain dan pemindaian TOFD dari bagian produk yang diuji.

Penggunaan perangkat tersebut mungkin tidak sangat berkualitas spesialis, karena penyesuaian dan kalibrasi membutuhkan waktu kurang dari 5 menit, dan fungsi yang telah ditentukan memungkinkan pemeriksaan cepat dan memastikan kualitas hasil.

NOVOTEST UD4701PA memungkinkan pengguna untuk menilai status produk atau elemen struktural di situs dan tanpa pra-pengujian. Detektor cacat ini sangat diperlukan dalam industri seperti konstruksi, pembangunan mesin, produksi logam digulung, teknik tenaga, penelitian, kimia, pertambangan, dll.
