HPX High Penentration Ultrasonic Thickness Gauge

Made in USA
Dakota HPX DL+ High Penentration Ultrasonic Thickness Gauge
Click images to enlarge.
The HPX DL+ Ultrasonic Thickness Gauge is designed for use on materials that are difficult for sound to penetrate, due to the lack of material consistency, grain structure, and overall thickness. Multiple high voltage pulser options, as well as filters tuned for lower frequency transducers (500 kHz – 10 MHz), the HPX compliments our product range by adding additional material types to our list of application possibilities.

Typical applications are fiberglass sheets, pipes, storage tanks, aerospace composites, boat hulls, conveyor belts, composite plastics, etc. There are a variety of features and tools to accommodate a number of material types and applications.

The electronic platform is FPGA driven for speed and accuracy. The screen refresh rate of 25 Hz contributes to the overall responsiveness of the gauge. The built-in data logger has two file format options, grid or sequential, and is equipped with an internal 4 GB SD card for memory. Connectivity to a standard PC or Apple via USB-C, and used in conjunction with our Windows® PC or OSX reporting software available for download.
