Dakota FX80 Benchtop Flaw Detector (DFX-8)
Product Description
Designed for use in the laboratory, these gauges are the tool you need for all your flaw detecting needs.
The Dakota FX80 Bench Top Ultrasonic Flaw Detector is available in two models: Dakota FX80-DL Bench Top Flaw Detector and Dakota FX81-DL Bench Top Flaw Detector.
The time corrected gain (TCG) feature automatically compensates for sound attenuation through a material, further increasing the performance of the gauge.
Within the grid batching of the Dakota FX80 Flaw Detector the user has the capability to enter ‘OBSTRUCT’ on to the grid for easy identification of inaccessible locations to measure.
The Dakota FX80 Ultrasonic Flaw Detector has a 6Gb internal memory and an external SD slot which allows up to 64Gb with full data logging via RS232 data output to DakMaster™ data management software.
