The new HST-Lite scanner is the perfect choice for cost-effective, TOFD inspections when signal quality is important. The combination of magnetic wheels and spring-loaded probe holders offer the stability required to perform high quality, one-line inspections. The scanner can be operated using only one hand, and will attach to ferromagnetic surfaces even when in an upside-down position. The scanner's position can be encoded around the circumference of pipes as small as 4.5 in. (114.3 mm) OD, as well as on flat surfaces. Adjustment of the different scanner components can be performed without tools.
