Description

BRK BT-T7 Through-Coating Ultrasonic Thickness Gauge

All BRK meters and probes ship direct from the manufacturer and require 5-10 business days for shipping.

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.
