Click images to enlarge.
The powerful new DFX-8 combination Flaw Detector and Thickness Gauge is ideal for a wide range of measurement applications. The DFX-8 features a large QVGA display with 60 Hz refresh rate. For flaw professionals it includes DAC, AWS, TCG, DGS sizing toolkits. When functioning as a thickness gauge it can measure in Pulse-Echo, Echo-Echo and other advanced modes for accurate measurements on coated and uncoated materials.

The DFX-8 has 4gb of internal memory to store readings in Grid or Sequential data formats. Data can be acquired via USB or SD card.

The DFX-8 combines the two types of gauges into one powerful and full featured instrument, that's equipped with a number of comprehensive toolkits to provide the user the arsenal necessary to address a number of common field applications.

also known as FD800

Features
