BRK BT-T7 Through-Coating Ultrasonic Thickness Gauge

The BRK BT-T7 is a professional-grade ultrasonic thickness gauge engineered for non-destructive measurement of base material thickness without removing surface coatings. It accurately measures true substrate thickness through paint, epoxy, galvanizing and corrosion layers up to 5 mm thick, significantly reducing inspection time and eliminating surface preparation.

Utilizing advanced ultrasonic pulse-echo technology, the BT-T7 delivers high-precision readings across steel, aluminum, plastics, glass and other homogeneous materials. Its rugged housing, high-resolution display and long battery life make it ideal for demanding industrial inspection and maintenance environments.

• Through-Coating Measurement Mode
