Ultrasound measurement device


Overview Image


The SDT ULTRAChecker is an ultrasound solution specifically designed to utilize the complete range of second generation SDT ultrasound sensors, both airborne and structure borne, featuring a built-in preamplifier. With the audible rendering, it enables comprehension inspection, while the real-time display of RMS values, in either a bar graph or numerical format facilitates immediate diagnosis.
