UD4-TM - universal multipurpose device of nondestructive control for diagnostics strategically vital objects of the industry, air transport, railway infrastructure combining general techniques of NDT, and specialized applications. "Ultrasonic kit". It is efficient for metalwork and CFR composites (carbon fiber) diagnostic. "Resonant kit". Identifies stratifications in composites, and gaps within the objects glued from the ferrous or composite materials. "Eddy current kit". Identifies superficial and subsurface defects in materials from ferromagnetic and not ferromagnetic alloys (sheets). It is completed with scanners and probes depending on the problem complexity of measurement procedure if necessary for various conditions. Sphere of application - the Railway industry, subway, oil and gas, power (including atomic), metallurgical, machine-tool construction, mechanical engineering, aircraft industry, shipbuilding, automotive industry.
