Where it is used
Typical tasks
- Remaining wall thickness of corroded pipes and vessels
- Precision thickness gauging in manufacturing
- Support for instruments already in service
Overview
The 38DL PLUS is a previous-generation general-purpose ultrasonic thickness gauge from Olympus. Olympus's industrial business now operates as Evident, and the manufacturer redirects the 38DL PLUS page to its successor, the 39DL PLUS, which refers to the 38DL PLUS as its predecessor.
This page is kept for users who already have a 38DL PLUS in service: for transducer selection, calibration and replacement planning.

What to choose instead of the 38DL PLUS
| Task | Instrument |
|---|---|
| General thickness gauging, corrosion and precision | 39DL PLUS |
| Compact gauge with options as needed | 45MG |
| Simple corrosion checks | 27MG |
| High-frequency and multilayer measurement | 72DL PLUS |
Supply in Kazakhstan
