Dakota NDT CMX Series Corrosion Thickness Gauge

Ultrasonic corrosion thickness gauge family that measures material and coating thickness (ThruPaint™ / PECT), with B-Scan, optional A-Scan, high-speed scan, 4 GB logging, and DakMaster™ download — from CMX1-DL through color CMX3-DL.

Key advantages

Material + coating — PE, EE (ThruPaint™), PETP, EEV, CT, and PECT modes for coated corrosion surveys.
Display options — Digits, scan bar, B-Scan; A-Scan (RF / rectified) on CMX2-DL / CMX3-DL; color AMOLED on CMX3-DL.
4 GB datalogging — Sequential and grid batches; DakMaster™ software; USB.
Inspection tools — Limit alarms, differential mode, high-speed scan (up to 250 rdg/s on CMX1-DL), 64 user setups.

Typical applications

Corrosion surveys on coated pipe, vessels, and structural steel.
Pit/flaw screening with PE mode and optional prove-up flaw mode (CMX2/3-DL).
Grid-based thickness mapping with downloadable reports.

Selection guide

CMX1-DL (Z-171-0005) — Greyscale; dual-element 1–10 MHz; scan to 250 rdg/s; no A-Scan/flaw mode.
CMX2-DL (Z-172-0005) — Greyscale; A-Scan; gates; damping; flaw prove-up; dual/single element 1–20 MHz; scan 50 rdg/s.
CMX3-DL (Z-187-0005) — Color AMOLED; A-Scan portrait/landscape; same advanced UT feature set as CMX2-DL.
Ranges (typical) — PE/PETP/PECT material 0.63…1219.2 mm; EE 2.54…152.4 mm; CT 0.01…2.54 mm (transducer-dependent).
Power — 3×AA or USB; −10…60 °C; 63.5 × 165 × 31.5 mm; ~383 g.
Calibration — Factory NIST / MIL-STD-45662 traceable certificate as standard.

Common mistakes

Ordering CMX1-DL when A-Scan/gates/flaw mode are required (need CMX2/3-DL).
Ignoring transducer selection — range and accuracy depend on probe and material.
Skipping coating mode (EE/PECT) on painted assets and reading coating as metal.

FAQ

Q: Can it ignore paint? A: Yes — Echo-Echo (ThruPaint™) and related modes measure material thickness through coating; PECT shows material and coating together.

Q: What should I send for a quote? A: Model (CMX1/2/3-DL), transducer, quantity. Compatible with systems using Dakota CMX if you need a drop-in check — we do not claim authorized-dealer status.
