Through Coating Ultrasonic Thickness Gauge

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 Measures base metal thickness through coatings up to 5 mm thick without removal. Extended Measurement Range 0.7 to 500 mm in standard mode on steel. 3 to 50 mm in through-coating mode. High Precision Performance Resolution of 0.01 mm with accuracy of +/-(0.6%H + 0.05) mm. Adjustable Sound Velocity Velocity range from 500 to 18,000 m/s for material calibration flexibility. Selectable Units Displays readings in millimeters or inches. Rechargeable Power System Integrated Li-ion battery providing over 160 hours of operation with backlight off. Industrial-Ready Construction Compact, durable housing designed for field inspection use. Typical Applications Corrosion monitoring in pipelines, tanks and pressure vessels Marine hull and ship structure inspection Structural steel thickness verification Oil, gas and petrochemical facility maintenance Manufacturing and fabrication quality control What's Included BT-T7 thickness gauge Standard 10 mm ultrasonic probe Calibration block Charging cable Carrying case User manual Specifications Measurement Range (Standard Mode) 0.7-500 mm on steel Through-Coating Mode Range 3-50 mm on steel (through coatings up to ~5 mm) Velocity Range 500-18,000 m/s Resolution 0.01 mm Accuracy +/-(0.6% H + 0.05) mm (H = actual thickness) Measurement Modes Standard & Through-Coating Units Metric (mm) / Imperial (inch) selectable Display High-definition LCD Power Supply Rechargeable Li-ion battery Battery Life 160 hrs (backlight off) Dimensions (LxWxH) 145x70x32 mm Material Compatibility Steel, aluminum, copper, plastics, glass, composites, alloys Probe Options Standard 10 mm probe, micro probes, coarse-grain and high-temp probes available
