Dakota NDT CMX3-DL A/B-Scan Material and Coating Thickness Gauge with AMOLED Color Display
SKU: Z-187-0005
The top of Dakota's CMX range: a corrosion thickness gauge that measures material and coating thickness at the same time, with a live A/B-scan on a bright AMOLED color display, 4 GB of memory and USB-C connectivity.

The Dakota NDT CMX3-DL combines the ruggedness of the CMX series with the analytical power of a flaw detector. It measures material and coating thickness at the same time while still locating pits, flaws and defects in the material, so inspectors get the full picture of a coated structure without removing the coating.
Its 1/4 VGA AMOLED color display shows real-time A-scan (RF or rectified) and B-scan cross-section views, with switchable portrait and landscape A-scan layouts. A 100 MHz DSP platform with two channels, 4 GB of internal memory and USB-C connectivity make it a top choice for petrochemical, power generation and aerospace inspection.
Key Features
 | A/B-scan scope on an AMOLED color displayVerify every reading on the live A-scan in rectified (+/-) or full RF view, in portrait or landscape. The time-based B-scan draws a cross-section of the back wall at 10 to 200 readings per second, and three independent gates and a 60 Hz color refresh keep signals clear and responsive. |
Built for the Field
Coating and material in one reading
In Pulse-Echo Coating (PECT) mode, the CMX3-DL displays material thickness and coating thickness separately in a single reading, while still detecting pits and flaws.
Six measurement modes
Pulse-Echo for bare metal, Pulse-Echo Coating, temperature-compensated Pulse-Echo for hot surfaces, Echo-Echo and Echo-Echo Verify for thru-paint readings, and Coating Only.
Powerful two-channel electronics
A 100 MHz DSP platform using FPGA technology drives dual pulsers and receivers at up to 250 Hz PRF. A 110 dB gain range, automatic gain control and linear time dependent gain with adjustable slope handle difficult materials, with single, dual, delay line and pencil probes.
Automatic setup
Automatic probe zero, probe recognition and temperature compensation get you measuring faster with fewer setup errors.
Scanning, alarms and QC tools
High-speed scan captures up to 50 readings per second and displays the minimum thickness found. Differential mode shows the deviation from a nominal value, and limit alarms with an LED indicator flag readings outside your tolerances.
Data logging and connectivity
Store readings with A/B-scan images on 4 GB of internal memory, save 64 user-defined setups, and connect to a PC over USB-C, which also provides line power. PC software and a data transfer cable are included.
Rugged and made in the USA
An extruded aluminum body with gasket-sealed, nickel-plated end caps weighs just 383 g (13.5 oz) and works from -10°C to 60°C.
