72DL PLUS™ Ultrasonic Thickness Gauge

The Olympus 72DL PLUS™ ultrasonic thickness gauge delivers precision thickness measurements at high speed in a portable, easy-to-use device. With fast scanning, advanced algorithms, and our lowest-ever minimum thickness capability, you can confidently measure the thickness of very thin layers in the most challenging applications.

72DL PLUS thickness gauges are available in Standard Frequency and High-Frequency models. The High-Frequency model can measure ultra-thin materials, including multilayer paint, plastics, metals, and coatings, and the Multilayer Measurement Software can simultaneously display the thickness of up to six independent layers. All 72DL PLUS models have the features to perform fast, accurate thickness measurements:

  • Digital filters enable an excellent signal-to-noise ratio to accurately measure noisy materials (e.g., fiberglass)
  • High-resolution touch screen is easy to use and see from various angles
  • PC Interface Application integrates your workflow, inspection management, alerts, and data analysis
