A compact handheld ultrasonic pulse velocity and pulse echo tester and low-cost tomograph is designed for ultrasonic thickness measurements and flaw detection of concrete and reinforced concrete constructions and rocks. The flaw detector represents an compact electronic unit is equipped with a large high-contrast TFT display and a keyboard. Despite multifunctionality the instrument is easу to use due to its intuitive interface and icons menu providing quick access to main settings and functions of the instrument.
