The μTOFD scanner is a single-axis coordinate scanner that, with the help of the UltraScan 5 system, is used to inspect welds on pipes and flat surfaces. With the rubber wheel on the encoder shaft the testing material can be steel as well as non-magnetic stainless steel.

A built-in water-proof pre-amplifier can be used for weak signal to provide the high quality signal for UT system. This is very helpful in some difficult testing conditions such as using 15 MHz TOFD probes and inspections on stainless steel.

In addition it can be used for pulse/echo mode. Other accessories include extended cables and coupling kits. The coupling kit consists of a couplant compressor, tubing, a Y-connector, and a flow-control valve. The 100-foot and 200-foot extension cables are built with differential line drivers and receivers which ensure the cables' reliable operation without attenuation. The TOFD scanner is designed to work with UltraScan 5, an ultrasonic inspection and analysis system. The system includes a portable computer containing an all-in-one pulser/receiver and high speed digitizer card.
