The Extech TKG250 Color Waveform Ultrasonic Thickness Gauge/Datalogger is a rugged, handheld instrument designed for non-destructive wall thickness measurements, primarily in steel and metal structures. With advanced features like a vibrant color LCD, A-scan live waveform display, and B-scan capabilities, it provides reliable and detailed thickness readings in real time.
It builds upon the TKG150 model by adding enhanced data review tools including file comparison and a grid-based review of saved readings. Ideal for quality control and maintenance applications, the TKG250 helps detect thinning due to corrosion or erosion without needing access to both sides of a surface. The built-in non-contact voltage detector adds another layer of functionality and safety for field technicians.
