Intelligent Digital Multi-channel Ultrasonic Flaw Detector HFD-248
Intelligent Digital Multi-channel Ultrasonic detector HFD-248 uses
the most advanced digital electronic technology and ultrasonic
technology. With modern design, steady performance, easy operation
and favorable price features, it is welcomed in overseas markets.
Detection channels can be 1,2,4,8,16, 32 optimal. There are two
options: one is ultrasonic detecting system with portable
ultrasonic equipment, another is ultrasonic detecting system with
LCD display.

Application:
The instruments can be widely used for titanium tube, zirconium
tubes, seamless steel tubes, welded gas and oil pipelines,
nonferrous metals, ferrous metals and some other non-metallic
pipes, bars, plates ,and the rail automatic (or semi-automatic)
non-destructive ultrasonic testing.
Features
# Independent transmitting channel and switched receiving channel.
Casual combination and recycle operation are all available.
# With own R&D Digital equipment, powerful function
# Simple configuration, and flexible connection towards the
hardware, and 128 channels testing available via various
Communicating junction modes.
# Motor control and other I/O ports reservation is available on the
condition that the testing projects needs is satisfied.
