——New Generation General-Purpose Digital Flaw Detector

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

The CTS-4020E represents the persistent fine tradition of SIUI: innovative technology,
advanced process, small size, lightweight, powerful functions and easy operation.

Innovative Technology
Continuous innovation and endeavor towards world-class technology is SIUI's consistent goal. The CTS-4020E combines all good performance
of a large ultrasound system in very small size: at least 63dB detection sensitivity surplus will meet detection demand for large forged pieces or
coarse-crystal material; LAN Ethernet port for real-time communication with a PC (Host) and remote control; Cine loop function for recording
dynamic scanning process; The simple and convenient interface wave tracking function is good for immersion detection; Together with new
techniques and new functions such as DAC, TCG, RF echo display, large memory and USB port, the CTS-4020E becomes a handy ultrasonic
flaw detector with excellent performance.
