FD700 Mini Flaw Detectors

The hand-held FD700 flaw detector range combines state-of-the-art flaw detection with advanced material thickness capabilities.

The Elcometer FD700 Mini Flaw Detector is available in two models: FD700+ and FD700DL+.

Whether you are on-site or in the laboratory these gauges are the tool you need for all your flaw detecting needs.

The time corrected gain (TCG) feature automatically compensates for sound attenuation through a material, further increasing the performance of the gauge.

The FD700DL+ stores up to 8,000 readings with A/B-scan images in alpha numeric batches with full data logging via RS232 data output to ElcoMaster® data management software.
