Guide: Selecting the Right Elios 3 UT Probe According to the Conditions of the Test Material 

Discover the different types of ultrasonic thickness gauges compatible with the Elios 3 and how to select the right one depending on the condition of the test material. 

The Elios 3 drone is a world-leading example of how robotics can be used to simplify and improve industrial
inspections, including deploying non-destructive testing. In this guide, we explain how the ultrasonic testing (UT)
probes compatible with the Elios 3 should be used according to the job at hand. This document is a comprehensive resource, providing straightforward tables and a flowchart alongside in-depth explanations about the different probe types and available measurement modes. 

The Elios 3 supports a single crystal probe in addition to three twin crystal probes. Over the course of this guide, you will find a flowchart outlining the correct uses for each ultrasonic probe, in line with guidance from both Flyability and the UT manufacturer, Cygnus Instruments.
