Conventional ultrasonic flaw detector EPOCH™ 700

for NDTportabledigital

Short description
The EPOCH™ 700 is a conventional ultrasonic flaw detector combining 24-bit A-scan digitization, a modern touchscreen, a dedicated adjustment knob and direct-access function buttons. Engineered for field inspections, it supports open .nde files and onboard A-scan recording for verifiable digital inspection records.

Overview
The instrument delivers high‑resolution signal acquisition and clear data in high-noise environments. A hybrid interface (touchscreen + physical knob + buttons) enables efficient operation with gloves and in adverse conditions. Open-format .nde support and enhanced onboard reporting simplify data transfer and traceability.

Key capabilities

• 24-bit A-scan digitization with minimum 1024 samples per A-scan and amplitude display up to 0–800% full-screen height
• High-dynamic-range receiver to reduce saturation and clipping
• High-resolution 7-inch display for precise A-scan rendering and readable overlays
• PerfectSquare™ tunable square-wave pulser (20 ns–5000 ns) with pulse voltages 100/200/300/400 V and selectable damping
• More than 20 fully digital filter sets (narrowband, wideband, low-pass)
• Full suite of sizing methods: DAC/TCG (ASME, JIS, CNDAC, custom), DGS/AVG, AWS D1.1/D1.5
• Onboard A-scan recording up to 30 s at 60 fps and support for open .nde file format
• IP65 enclosure and MIL‑STD shock/vibration testing for field reliability

Designed for inspectors and workflows
Ergonomically balanced (≈1.8 kg including battery) for one-handed operation. Features include ray-trace visualization for part/weld setup, visual sizing configurator, 64 GB onboard storage, Wi‑Fi and Bluetooth for wireless transfer, and direct-from-gauge reporting to streamline inspection workflows.

Applications
Suitable for weld inspection, composite inspection, component and metal inspection, manufacturing quality control, and demanding nuclear inspections. EPRI PDI qualifications and support for qualified probes (e.g., C542, C571, C5011) enable use in critical applications.
