The digital ultrasonic flaw detector CTS-4020E is suitable for various detection demands,such as forged pieces, welding lines and airplane parts.

• Probe frequency testing function.
• Probe angle (K value) measuring function.
• Variable PRF: avoid reverberation signals during flaw detection.
• Large capacity lithium battery pack for continuous operation over 6 hours.
• High-brightness color TFT LCD, bringing optimized effect for reading and measurement.
• Color differentiation display function for second echo signals, when detecting with an angle probe.
• Ethernet communication for achieving real-time communication with a PC(Host) and remote control
• Large memory for saving up to 1000 data sets, including wave forms,curves,parameters, test reports, etc
• USB port for saving system stored data and data waveforms to a USB disk,as well as easy printing test reports.
• 10 waveform and character colors are available for selection.
• RF (Radio Frequency) echo display: good to thin-wall material measurement,academic research or qualitative analysis.
• Peak value memory function and echo compare function:useful for fast scanning, measurement and comparison on workpieces.
• Cineloop function for recording dynamic scanning process.
• Operating frequency range: 0.5~15MHz, highlighting advantages of high sensitivity and broadband.
• Interface wave tracking function: Immersion detection or precision measurement can be easily achieved through the logic relation between gate A and B. 
• Complete DAC and TCG curve function: convenient for echo evaluation,suitable for on-spot detection, such as detectionon large forged pieces and coarse-crystal material.
