GE KrautKramer USM GO portable ultrasonic flaw detector weighs less than 2 pounds, is robust and well sealed meeting IP67, and built to withstand the rigors and use in harsh industrial environments. It is simple to operate using one hand and its large, high resolution (WVGA) A-Scan display and outstanding ultrasonic performance are essential for inspections based on common codes and standards. The first choice when top UT performance, combined with ultra-portability and one-hand operation is required.

Ergonomically Designed with the User in Mind
The USM Go ultrasonic portable flaw detector has been ergonomically designed to provide an instrument that is light, small and easy to use in the harshest of inspection environments.

GE KrautKramer USM GO

Features:

• Portability
  • Small size, lightweight, robust, dust- and waterproof construction allow the instrument to be easily operated in confined spaces, areas of difficult access, and in harsh environments.
  • Can be operated with one hand, leaving other hand free for other tasks, such as maintaining probe in optimum position or holding on to ladders.
  • Light enough to be carried throughout a whole day’s shift.
  • Battery provides up to 6 hours operation. Can be recharged on- or off-board.
  • Several accessories to improve mobility are available: wrist strap, shoulder harness, belt holster.
• Easy-to-Read Screen
  • A display screen that is the same size as those in other GE flaw detectors, even though the instrument is much smaller than other instruments in the range
  • An 800 x 480 pixel display, which is better resolution than a standard DVD.
  • A screen with an optimized aspect ratio to ensure highly defined echo separation.
  • A screen that can be easily viewed, whether hand-held or desk-mounted.
  • A screen that has been ergonomically sized to help reduce eyestrain.
  • An integrated stand allows the user to optimize the viewing angle, when the instrument is desk- or benchmounted
  • AutoGate Threshold for faster measurement with optimum accuracy.
  • A-scan freeze mode function (for gate A and B) fascilitates working in difficult ergonomic conditions.
  • Display measurement indicators show both amplitude and distance to reduce risk of error
• Ease of Use
  • Pressure-sensitive joystick imported and adapted from the successful range of remote visual inspection and ultrasonic equipment offered by GE.
  • All controls within fingertip reach. User can dedicate function keys according to preference
  • A “Flip” function allows the instrument to be used equally well by left-handed and right-handed people.
  • A standard USB connection to allow data to be downloaded from the flaw detector for further analysis or storage.
  • The instrument’s 2 GB memory can be easily exchanged by SD cards up to 16 GB
  • Reports are produced in jpeg format so there is no need for special reading software.
  • Printable summary list of all parameters
  • Easy directory management on SD cards
  • Built-in menu customization tool allows to adapt the menu structure to two levels of users.
  • Smart notes function increases reporting efficiency.
  • Yearly calibration reminder for efficient quality management

Increasing Productivity
The USM Go features intuitive operation so there is virtually no time-consuming, learning curve.

You are productive from the moment you pick it up!

There is no need to refer to the manual, as clear instructions are provided as you go along. Navigation is simplified using the proven graphical user interface (GUI) and the innovative joystick, allowing one-handed operation for fast and accurate adjustment.

Other features allowing increased productivity are:

• A robust molded rubber casing to withstand the harshest environments and significantly reduce downtime. The instrument is dust- and waterproof to IP67 and is tested to withstand shock and vibration
• A simple on-board data logger to collect and save thickness measurements or eventually attach the corresponding A-scan image.
• Backwall Echo Attenuator (BEA) helps to find very small defects improving detectability.
• Automatic Gate Threshold for the 2 gates ensuring accurate measurements made under the same conditions
• Video recording upto 8 minutes allows live reporting.

High UT Performance

• State-of-the-art electronics, including digital amplification, for a wide range of application benefits.
• A wide Pulse Repetition Frequency range allows use at low PRF to inspect forged parts without any “ghost” echoes and to inspect welds at high PRF when fast and regular scanning movement is required.
• Precise Time of Flight indication in µs.
• TrueDGS compatible.

Versatile and Upgradeable

• Customized versions of the USM Go are also available, specially adapted to meet specific inspection codes or applications. For example, an optional square wave pulser can be supplied for applications involving the inspection of highly attenuative material. The versions shown in the table are currently available.
