TUD220 ultrasonic flaw detectorDetailed product description：

The TUD220 ultrasonic flaw detector is a portable industrial non-destructive testing instrument that can quickly, conveniently, non destructively, and accurately detect, locate, evaluate, and diagnose various internal defects (cracks, porosity, pores, inclusions, etc.) in workpieces. It can be used in both laboratories and engineering sites. It is widely used in boiler, pressure vessel, aerospace, aviation, power, petroleum, chemical industry, offshore oil, pipeline, military industry, shipbuilding, automobile, machinery manufacturing, metallurgy, metal processing industry, steel structure, railway transportation, nuclear power, universities and other industries.

Features:
Ultra high sampling rate, RF waveform details are fully displayed, with a minimum display range of 2.5mm.
Simultaneously equipped with USB and RS232 serial communication ports.
• Key menu operation
All software of the whole machine can be upgraded online through the communication port. Users can download local embedded software from the Times website and upgrade it themselves, which is convenient and fast.
• Have an electronic clock calendar.
The large capacity storage can store up to 400 A-scan graphics and parameters, as well as 40000 thickness values.
Using high-capacity lithium-ion batteries, with no memory and a continuous working time of about 6 hours.
Equipped with three adjustable bias DAC curves, it can adapt to the drawing standards of DAC curves in different industries.
EL high brightness graphic dot matrix display screen, with no viewing angle limitation, unaffected by temperature and sunlight.
• Equipped with dual gate setting and alarm function. The position and width of the gate can be set arbitrarily on the screen, with three alarm modes: incoming wave, lost wave, and automatic.
• Can switch between single probe and dual probe inspection modes at will.
• Waveform display: positive half wave, negative half wave, full wave, and RF
The probe damping can be switched between 50, 150, and 400 through the menu selection.
DAC curves can be automatically generated using standard test blocks.
• It has linear suppression function, with a screen height of 0-80% and a step distance of 1%.
• It has printing function and can print thickness reports and wave amplitude curves through a serial printer.
Can perform screen hard copy, copy and print the graphics and menus on the current screen.
Capable of communicating with a PC and equipped with powerful Windows data processing software.
