Key parameters
Fits weld and material inspections that need one handheld instrument for both ultrasonic flaw detection and advanced thickness (including coating) — DAC/AWS/TCG/DGS sizing, A/B-scan views, and 4 GB logging in an IP65 aluminum case.
Key advantages
- Two instruments — Flaw detector + thickness gauge with simultaneous material/coating capability in thickness mode
- Sizing toolkits — DAC, AWS D1.1, TCG, DGS; detection Z-Cross / Flank / Peak
- PRF / display — 8 Hz–2 kHz adjustable PRF; 60 Hz refresh; 320×240 AMOLED sunlight-readable
- Thickness modes — P-E, PECT, PETP, E-E ThruPaint, E-EV, Coating Only; auto probe zero/recognition/temp comp
- Logging — 4 GB internal grid/sequential; USB; DakMaster software path
Typical applications
- Weld inspection with angle-beam TRIG path/depth/surface-distance display
- Corrosion and coated-asset thickness with ThruPaint echo-echo
- Shop or field NDT needing hi/lo alarms and differential QC mode
- Jobs requiring EN 12668-1 compliant flaw-detector performance class
Selection guide
- Form — Handheld 63.5 × 165 × 31.5 mm; ~397 g with batteries; IP65
- Pulser — Two adjustable square-wave pulsers; 100–200 V; pulse width 40/80/400 ns
- Thickness ranges (dual/single) — P-E about 0.025–96 in typical; E-E about 0.050–4.0 in; coating 0.0005–0.100 in (OEM; probe-dependent)
- Power — 3× AA or USB; alkaline ~12 h / NiMH ~12 h / NiCad ~5 h class
- Standards — Thickness factory cal traceable to NIST & MIL-STD-45662A; flaw EN12668-1 compliant
Common mistakes
- Ordering FX71 when higher pulser voltage / extra narrow bands of FX81 are required
- Assuming ThruPaint range equals bare P-E — E-E windows are narrower
- Leaving transducer type blank (single contact / dual / delay / angle)
- Skipping DakMaster / USB cable needs when reporting workflow matters
When to RFQ / what to tell us
- Primary role (flaw vs thickness), weld code (AWS/DAC/DGS), and transducer types
- Coating ThruPaint need, logging format, quantity
- Ship-to and whether FX81 comparison is desired

FAQ
Q: Is FX71-DL only a thickness gauge? A: No — it combines a flaw detector (DAC/AWS/TCG/DGS) with advanced thickness modes including ThruPaint.
Q: FX71 vs FX81? A: FX81 is the higher FX80-series class with tone-burst pulsers up to 400 V and additional receiver bands — compare if high-energy/low-frequency work is needed.
Q: What should I send for a quote? A: Flaw vs thickness priority, codes/probes, coating need, quantity, ship-to. Compatible with systems using Dakota FX71-DL — we do not claim authorized-dealer status.
