Product Description

Product Overview

The TFD900 Ultrasonic Flaw Detector is an ultra-light, handheld UT instrument delivering outstanding performance. Compatible with EN12668-1:2010, it is engineered for precision flaw detection in demanding industrial environments.

The instrument features a 5.6-inch TFT display with full WVGA (800*480) resolution, ensuring excellent visibility even outdoors or under strong sunlight. Its advanced "square wave drive" technology delivers the sensitivity and resolution professionals demand. Weighing only 0.9 kg, the TFD900 is designed to be carried and operated like a hand tool for instant inspection tasks — making it a superior choice compared to conventional counterparts.
