Ultrasound – Portable Flaw Detectors - USM Go / USM Go+

Corrosion Monitoring – Rightrax upstream solutions


The well-established and proven ultrasonic flaw detector USM Go is available with joystick operation or as the new USM Go+ with arrow-key operation. The USM Go and the new USM Go+ are both extremely portable and robust ultrasonic flaw detectors. Both units have a small protected hand-held housing with the biggest A-Scan display in its class and features which are essential for inspections based on common codes and standards.

The USM Go is the first choice when top UT performance, combined with ultra-portability and one-hand joystick operation is required and furthermore has the option to upgrade to a thickness gauge.

The new USM Go + is the youngest member of the USM Go family equipped with an arrow-keypad and the latest industrial electronics. The state-of-the-art technology contributes to the improved UT performance of the new USM Go + .One prime example is the outstanding Near Surface Resolution which allows a reliable detection of defects located just below the surface of the test piece.

Apart from the different operational devices the joystick or the arrow-keypad, the operation and the menus of both instruments are the same. The accessories are inter-changeable with both instruments. And even the stored instrument settings of the USM Go can be used with the new USM Go + and vice versa which will ease any ultrasonic inspector’s work but will ensure that proven settings can continue to be used with new equipment and even shared with other USM Go / USM Go+ inspectors.

  • 850 g (1.87 lb.) total weight incl. batteries.
  • A-Scan recording as video on SD-Card.
  • trueDGS® Defect Sizing with highest available accuracy.
  • Back wall Echo Attenuation helps to detect extreme small defects.
  • IP67 Protection.
  • 800 x 400 bright colour LCD (>200cd/m²).

A standard USB connection to allow data to be downloaded from the flaw detector for further analysis or storage. The instrument is standard delivered with a 2 GB SD memory card (can accomodate up to 16GB card size).

Reports are produced in jpeg or bmp format so there is no need for special reading software.

A simple on-board data logger to collect and save thickness measurements.


The USM Go/USM Go+ has been designed to provide flaw detection capability in inspection situations throughout the industrial and process spectrum, from aerospace to power generation and from the automotive sector to the oil and gas industry.
