digitalportablefor materials

Overview
The EPOCH 700 conventional ultrasonic flaw detector combines a 7-inch touchscreen with a dedicated adjustment knob and direct-access physical buttons for reliable field operation. It provides 24-bit A-scan digitization, a high-dynamic-range receiver, and support for open .nde files. The instrument is qualified for key EPRI PDI nuclear inspection procedures and is engineered for portable, verifiable inspections.

Key Features

• 24-bit A-scan digitization for high-resolution signal capture and amplitude measurements to 0–800% full-screen height.
• High-dynamic-range receiver to minimize saturation and clipping.
• PerfectSquare™ tunable square-wave pulser with selectable pulse voltages (100/200/300/400 V) and pulse widths 20 ns–5000 ns.
• Extensive digital filters (>20) including narrowband, wideband and low-pass options.
• Full set of sizing methods: DAC/TCG (ASME, JIS, CNDAC, custom), DGS/AVG, AWS D1.1/D1.5.
• Open .nde file format support and onboard A-scan recording (up to 30 s at 60 fps) with .nde export.
• Rugged IP65 enclosure; MIL‑STD shock and vibration testing; balanced ergonomics (~1.8 kg with battery).
• Built-in Wi‑Fi, Bluetooth and modern USB‑C connectivity for file transfer and reporting.

User Interface and Workflow
The instrument pairs a mobile-style menu UI with color-coded status and context-aware layouts. The dedicated adjustment knob provides smooth tactile control with center-click. Onboard tools include visual sizing configurator, ray-trace visualization and structured onboard reporting to streamline setup and documentation.

Applications

• Weld inspection across oil & gas, power generation, infrastructure and transport.
• Composite inspection for aerospace, New Space and automotive applications.
• Component and metal inspection for manufacturing quality control.
• Demanding nuclear inspections — qualified for multiple EPRI PDI procedures and compatible with qualified probes.

Inspection Reporting and Data Management
The EPOCH 700 supports folder-based file management with 64 GB internal storage, onboard structured inspection reports, and open .nde export for integration with analysis platforms. A-scan sequences can be recorded, reviewed onboard and exported for traceable records.
