The TFD806C is a professional-grade ultrasonic flaw detector engineered for accurate, high-speed inspection in demanding industrial environments. With an intuitive dialog-driven interface, advanced signal processing, and a rugged IP65-rated housing, it delivers reliable defect detection and precise flaw sizing across a wide range of applications.

• ▸User-friendly dialog interaction simplifies operations such as calibration and curve generation.
• ▸Complete toolset: DAC, AVG, TCG, and AWS evaluation functions built in.
• ▸Pulse repetition frequency 10–2000 Hz with precise adjustment for high-speed scanning without missed indications.
• ▸High signal-to-noise ratio with clear, stable echoes and anti-noise design — ideal for tough working conditions.
• ▸12-bit AD conversion and high-speed sampling produce detailed echo diagrams; sensitive enough to detect tiny flaws.
• ▸Supports probe frequencies up to 20 MHz for demanding inspection tasks.
• ▸IP65-rated protective rubber casing with damping support that allows the unit to stand at any angle.
• ▸Up to 15 hours of battery life per charge for full-day field operation.

• ▸Automated display of precise flaw location (Depth d, level p, distance s, amplitude, sz dB, φ).
• ▸Flaw sizing: automatic flaw sizing using AVG or DAC/TCG, speeding up reporting of defect acceptance or rejection.
• ▸Automated calibration of transducer zero-point, angles, front edge, and material velocity (V2 and two-hole).
• ▸Convenient creation and use of DAC/TCG and AVG to evaluate echoes; curves can be modified and compensated.
• ▸U-Disk connection provides unlimited memory.
• ▸15 built-in standards.
• ▸Bluetooth connection to mobile devices to generate and print detection reports on-site (optional).
• ▸AWS D1.1 support.
• ▸Curved surface correction feature.
• ▸Crack height measurement function.
• ▸Magnify gate: spreads the gate range over the entire screen width.
• ▸Auto-gain function.
• ▸Envelope: simultaneous display of live A-scan at 70 Hz update rate and A-scan envelope.
• ▸Peak Hold: compare frozen peak waveforms to live A-scans to easily interpret test results.
• ▸Scan Freeze: display freeze holds waveform and sound path data.
• ▸Alarm: beep and LED.
• ▸Real-time clock.
• ▸Fill echo.
• ▸Capture mark.
• ▸Echo color within the gate.
