Dakota FX81-DL Benchtop Flaw Detector (DFX-8+)

Product Description
The Dakota FX81-DL Bench Top Flaw Detector combines state-of-the-art flaw detection with advanced material thickness capabilities.
The Dakota FX81-DL Ultrasonic Flaw Detector, designed for laboratory use, is a high-performance tool tailored for precise flaw detection. It features Time Corrected Gain (TCG), which automatically compensates for sound attenuation in materials to enhance measurement accuracy. The gauge includes grid batching functionality, allowing users to mark “OBSTRUCT” on the grid to easily identify inaccessible measurement locations.
With 6GB of internal memory and an external SD slot supporting up to 64GB, it offers robust data storage, complemented by full data logging capabilities via RS232 output to DakMaster™ data management software. This makes the FX81-DL an efficient and reliable solution for laboratory-based flaw detection tasks.
