Dakota NDT HPX DL+ High Penetration A-Scan Thickness Gauge
SKU: Z-225-0001
Dakota's most powerful A-scan thickness gauge, with high-voltage pulsers and low-frequency filters for measuring fiberglass, composites, HDPE, rubber, castings and heavy-wall steel that standard gauges can't penetrate.

The Dakota NDT HPX DL+ is designed specifically for materials that are difficult for sound to penetrate, due to the lack of material consistency, grain structure or overall thickness. Multiple high-voltage pulser options and filters tuned for lower-frequency transducers (500 kHz to 10 MHz) let it measure fiberglass, carbon fiber, cast metals, rubber, HDPE, FRP, lead, and all steels and aluminums.
An A-scan waveform display lets inspectors verify every reading, and a built-in data logger with 4 GB of internal memory documents every survey. The kit comes ready to work with a custom 1" rubber delay line transducer, PC software and a foam-fitted carrying case.
Key Features
 | Power to penetrate difficult materialsPowerful high-voltage spike, square wave and tone burst pulsers drive low-frequency transducers deep into attenuative materials, and filters optimized for 500 kHz to 10 MHz help secure the back wall echo. It measures composites over 100 mm thick and steel up to 100 ft (30.5 m). |
A-scan verification and data loggingView the A-scan waveform to confirm every reading on difficult materials, with gain slope control and a 25 Hz screen refresh for a responsive display. A built-in data logger with grid and sequential file formats stores readings on 4 GB of internal SD memory. |  |
Built for the Field
Delay line transducer included
The kit's custom 1" × 0.5 MHz single-element rubber delay line transducer is built for high-penetration work on composites, plastics and other attenuative materials.
Fast, FPGA-driven platform
The FPGA-driven electronics deliver speed and accuracy, and the 25 Hz screen refresh keeps the gauge responsive while you scan.
Selectable resolution and wide velocity range
Choose 0.01" (0.1 mm) or 0.001" (0.01 mm) resolution, and set velocities from 310 to 18,542 m/s to suit virtually any material.
Easy reporting
Connect to a Windows PC or Mac over USB-C, and use Dakota's free reporting software to manage and report your data.
Rugged and compact
An extruded aluminum body with gasket-sealed, nickel-plated end caps weighs just 383 g (13.5 oz) with batteries and works from -10°C to 60°C. It runs on AA batteries or USB power.
