Alat Pengukur Keretakan Sambungan Hasil Las – NOVOTEST Flaw Detector UD4701PA

Alat Pengukur Keretakan Sambungan Hasil Las – NOVOTEST Flaw Detector UD4701PA – Instrumen pengukuran yang digunakan untuk mendeteksi cacat pada produk jadi, produk setengah jadi dan sambungan las, serta menentukan koordinatnya dan menggunakan DAC dan fungsi DGS. Dilengkapi dengan layar TFT warna kontras (resolusi 640 × 480), kandang yang dapat diandalkan, perangkat ini selalu siap untuk dioperasikan, baik di laboratorium maupun di lokasi dengan pengaruh lingkungan agresif seperti suhu, debu dan curah hujan.

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.
