Extech TKG150: Digital Ultrasonic Thickness Gauge/Data Logger

The Extech TKG150 is a compact and rugged digital ultrasonic thickness gauge equipped with advanced data logging capabilities. Designed for non-destructive testing (NDT), this meter is ideal for inspecting steel structures and detecting metal thickness without removing coatings or damaging the surface. Its durable handheld design makes it perfect for both field and industrial environments.

It features multiple operating modes, including Echo-to-Echo for painted surfaces, B-Scan for cross-sectional visualization, and Differential Mode for comparison against a reference value. The TKG150 also supports USB connectivity and software export, enabling users to store and analyze up to 100,000 readings and 5,000 waveforms.
