FD800 Bench Top Flaw Detectors

The bench-top FD800 flaw detector range combines state-of-the-art flaw detection with advanced material thickness capabilities.

Designed for use in the laboratory these gauges are the tool you need for all your flaw detecting needs.

The Elcometer FD800 Bench Top Flaw Detector is available in two models: FD800DL and FD800DL+.

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 FD800DL+ the user has the capability to enter OBSTRUCT on to the grid for easy identification of inaccessible locations to measure.

The FD800DL+ has a 6Gb internal memory and an external SD slot which allows up to 64Gb with full data logging via RS232 data output to ElcoMaster® data management software.
