72DL PLUS™ Ultrasonic Thickness Gauge

High-Speed, High-Frequency, High-Precision Measurements

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

Choose the Thickness Gauge Model That Best Suits Your Needs

Choose from Standard Frequency, High-Frequency, and the Multilayer Measurement Software options, depending on the application.

Standard Frequency model: offers reliable thickness measurements at high speed (2 kHz measurement speeds and a 60 Hz display update for A-scan) using single element transducers with a frequency range of 0.2 to 30 MHz

High-Frequency model: includes all the features of the Standard Frequency model, as well as up to 125 MHz transducer frequency support for measurement of ultra-thin materials

Multilayer Measurement Software: simultaneously displays up to six multilayer measurements

Choose Your Transducers

The 72DL PLUS thickness gauge is compatible with Olympus single element ultrasonic transducers with frequencies up to 125 MHz:

• 0.2–30 MHz range for the Standard Frequency model can measure materials at high speed for fast results
• 20–125 MHz range for the High-Frequency model can measure ultra-thin materials
