Ultra-portable ultrasonic flaw detector UCD-20 weighing less than 250 g is an easy-to-set-up and operate tool for testing in hard-to-reach places and in other conditions when the dimensions and weight of the tool are critical.
Despite the small size of the UCD-20, it has good performance, a modern frost-resistant TFT screen with three color schemes, including those for operation in bright sunlight, and all the main functions of a modern flaw detector.
In a special version, a full-functional thickness gauge mode is also available with all the functions of a professional thickness gauge with A-scan UDT-20.
