Dakota CMX10-DL – Top-of-the-Range Corrosion Gauge

The Dakota CMX10-DL is the top-of-the-range ultrasonic thickness gauge of the Dakota NDT family. The first instrument in its category with Full Wave Capture technology, it combines in a single compact instrument the functions of a corrosion gauge, a precision gauge and flaw prove-up with an angle probe. Equipped with an 800×480 colour TFT touchscreen display, a rechargeable Li-Ion battery, IP65 protection, a measuring range up to 1480 mm in PE and Second Layer mode for composite materials, the CMX10-DL is designed for professional NDT inspectors working in critical applications where full traceability, advanced documentation and dynamic signal analysis are non-negotiable requirements.

Positioning: the Dakota top of the range

The CMX10-DL is the pinnacle of the Dakota thickness gauge range and sits above the classic CMX series. It is designed to replace several traditionally separate instruments with a single platform:

• Corrosion gauge with A-Scan and B-Scan
• Precision gauge for thin thicknesses with ±0,001 mm resolution
• Flaw prove-up instrument with an angle transducer
• Data logger with full traceability (setup library, transducer library, calibration library)

Unlike traditional dedicated instruments, the CMX10-DL allows a single investment to cover corrosion inspections on tanks and piping, precision measurements on aerospace components and crack prove-up in welds. Its distinguishing feature is Full Wave Capture: all waveforms are recorded in memory together with the measurement, allowing retrospective analysis on a PC with DakMaster™.

Distinguishing features compared with the CMX series

• 800×480 colour TFT touchscreen display (vs. the monochrome LCD of the CMX series)
• Mixed operation: keypad + touchscreen + combination
• Smart rechargeable Li-Ion battery (vs. 2×AA on the CMX series) with 9-15h battery life
• IP65 protection (dust and low-pressure water jets)
• ODU Smart Port in addition to the classic LEMO-00 — automatic recognition of compatible ODU probes
• Second Layer mode (PE2/EE2) for multilayer composite materials
• Full Wave Capture: recording of complete waves in the data log
• Image Collect: load a photo or CAD drawing of the part via DakMaster™ and tap directly on the instrument to set the next measurement position
• Gain 0-74 dB in 0.1 dB steps with TCG (ramp or curve up to 16 points) and Auto80
• Adjustable pulser voltage 50-200V in 1V steps
• 3 gate filters: Flank, Zero-Cross, Peak
• Low Pass filters (10/20/30 MHz), High Pass (0.5/2.5/5 MHz) and Broadband
• Bluetooth LE in addition to USB
• Screen Share & Control for remote viewing
• DakMaster Mobile App compatible
• Made in United Kingdom

When to choose the Dakota CMX10-DL

• You work in critical applications that demand the highest level of documentation and traceability
• You need a single multifunction instrument for corrosion + precision + flaw prove-up
• You have to inspect multilayer composite materials (Second Layer mode)
• You want a colour touchscreen display for a modern, intuitive interface
• You want to integrate photos/CAD of the component into the inspection procedure (Image Collect)
• You require advanced documentation with A-Scan, B-Scan and video recordings saved in the data logs
• You have Level II/III certified personnel who benefit from dynamic analysis
• You work in environments exposed to dust and moisture (IP65)
• You require Bluetooth connectivity for integration with a mobile app

Supported measurement modes

Mode	Range (probe-dependent)	Typical use
PE (Pulse-Echo)	0,18 – 1480 mm	Standard measurement on clean surfaces
EE (Echo-Echo ThruPaint)	0,18 – 592 mm	Painted surfaces (coating ignored)
EEV (Echo-Echo Verified)	0,18 – 296 mm	Consistency check between multiple echoes
PE2 (2nd Layer PE)	0,18 – 1480 mm	Composite materials — layer 2 measurement
EE2 (2nd Layer ThruPaint)	0,18 – 592 mm	Composites with a coating

Full Wave Capture and Image Collect functions

Full Wave Capture

The distinguishing capability of the CMX10-DL is the complete recording of the ultrasonic waveform together with each stored measurement. This means an inspector can return to the office after a measurement campaign, open the data log in DakMaster™ and re-analyse any measurement as if acquiring it at that moment — repositioning the gates, changing the interpretation of an anomalous echo, exporting the waveform for reporting. This function drastically reduces the risk of having to go back into the field for uncertain measurements.

Image Collect: image-guided inspection

The Image Collect function allows a photo of the component or a CAD rendering to be loaded directly onto the instrument via DakMaster™. The operator taps on the CMX10-DL display at the position being measured, guiding the inspection visually. Each measurement is georeferenced on the image of the part — an approach that reduces annotation errors and speeds up final reporting.

Overlay Comparison

The CMX10-DL allows waveforms from different measurements to be overlaid in order to identify variations in the signal patterns that may indicate structural changes or critical areas — useful, for example, when comparing periodic inspections of the same asset.
