DC-4000 Gauge For Thickness Testing of Fibreglass & Composites

DC-4000 UT Gauge

We frequently receive requests for a cost-effective ultrasonic gauge and probe combination that can reliably measure the thickness of fibreglass. Our UT specialist recently took up the challenge and has sourced a gauge that meets this criteria!

The DC-4000 Gauge can be set up to reliably and consistently measure gel coated fibreglass, when coupled with the D1025 Probe. We have tested this on samples from 3 mm to 20 mm and are delighted with the results.
