Overview
72DL PLUS™ Ultrasonic Thickness GaugeHigh-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:

Measure the Thickness of Up to Six Layers for Multilayer Coatings, Paint, Plastics, and Other Materials
The Multilayer Measurement Software offers multilayer thickness measurements of up to six layers. Measurement settings for each layer—including material, velocity, target thickness ranges, and alarm thresholds—are easily accessible through the configuration workflow and touch-screen controls.
Workflow
Streamlined Thickness Data Collection and Processing
All 72DL PLUS™ models have built-in datalogging with up to 2 GB of data storage, along with convenient onboard file management features.
- On-screen alphanumeric keypad for file naming and editing report headers to organize your work
- File Manager menu makes it simple to review and edit application files, review and delete inspection data files, and see the inspection completion percentage; once a file is identified, it can be conveniently recalled
- Connect a foot switch for hands-free activation of the save/send data function
Easy Application Setup for Routine Thickness Measurements
For routine applications on simple or complex parts, store and recall settings in the My Applications menu to simplify the device setup process. This reduces manual selection and setting adjustments before each inspection, enabling efficiency and confidence in the measurement quality.
The My Applications menu makes it easy to create custom applications right from the gauge:
- Predefined configurations for single layer, multilayer, barrier, and reduction rate
- Menu guides you through each process step, from choosing the configuration for an inspection to setting up the transducer, material, alarms and alarm conditions, measurement mode, and the part map
- Applications are easy to recall—just turn on the gauge and the instrument shows the My Applications menu as the startup screen
For added flexibility, the PC Interface Application can also be used to create applications and send the files to different gauges on the production floor or across facilities.
Track and Visualize Thickness Changes with Versatile Measurement Layouts
All 72DL PLUS models include five measurement layouts, so thickness changes on a test material can be accurately tracked and visualized.
