USN 60 & USN 60L

NEW brighter display works at -20°C !
The USN 60 flaw detector series has been optimized for use in direct sunlight and operation at extreme temperatures. These new characteristics make the instruments ideally suited for outdoor use with its increased long battery operation time. Depending on the applications challenges, you have the choice between the USN 60 and the USN 60L version.

USN 60
Range 0.040” to 1100” (1 mm to 28 m) at steel velocity;
Pulse Repetition Frequency up to 6000 Hz

USN 60L  (replaces USN 58L)
Range is 0.040” to 480” (1 mm to 12 m) at steel velocity;
Pulse Repetition Frequency up to 2000 Hz

  • Extreme temperature use (-20°C to +55°C /-4°F to 130°F)
  • Easy to view in direct sunlight
  • 11 hours battery operation
  • Hi-resolution color LCD display produces “Analog Look and Performance” echo dynamics.
  • 4 selectable vibrant display color schemes to match lighting conditions.
  • Gates and gate functions are color coded for easy identification and adjustment.
Wide range of applications

A 6 kHz pulse repetition frequency, real-time analog and TTL outputs makes the USN 60 flaw detectors series ideal for a wide range of automated systems testing applications. The exclusive SmartView feature displays even the shortest echoes for critical scanning and rotating part inspections. The quality, durability, dependability and ease of use that you have come to expect of Krautkramer’s popular USN Series of instruments remains.

From rugged field inspections to high resolution thin measurements, long acoustically clean materials, and immersion systems, the USN 60 flaw detector family extends the range of applications that a portable instrument can perform. Furthermore the selectable 450V Square Wave Pulser satisfies a wide range of tough to penetrate applications, such as difficult to penetrate metallic applications and especially non-metals inspection like composite materials.

USM-Go +

A Flaw Detector that can also become a flexible Thickness Gauge...
The 4-way arrow keys control of the USM Go+ can be used left or right-handed. Large clear LCD, viewable in the brightest of light. Powerful, comprehensive ultrasonics allow extreme versatility for a wide range of applications, IP67 dustproof and waterproof.

The 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.

  • Video recording up to 8 minutes allows live reporting. Download the USMGO player free of charge and create your own .AVI video file. Great reporting tool for data transmittal.
  •  Auto Angle calculation validates the true effective angle of the wedge , automatically inputs value into the trigonometric flaw calculation
  •  A-scan freeze mode function (for gate A and B) facilitates working in difficult ergonomic conditions.
  •  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.
  •  Yearly calibration reminder for efficient quality management.

Upgrade your USM Go+ to the DMS Go+ thickness gage
The USM Go+ uses the same operating platform as the DMS Go+ thickness gage. By means of a simple software purchase your USM Go+ can benefit from all the DMS Go+ functionalities and perform advanced thickness gage readings with full data recording capabilities.This means that NDT personnel now need to carry only one inspection instrument to perform accurate and dependable thickness measurement and flaw detection. A further benefit of this dual modality is a significant reduction in operator training times.



·  Low cost

·  Easy to use

·  Long battery life

ECHO FD comes standard with 2 independent gates, DAC, AWS, API 5UE, B-scan software and 2 Gb of datalogging memory, 13 hour battery life with internal rechargeable batteries. 

ECHO FD also allows for one hand operation with a simple, intuitive user interface all for the price of equal or less than you are paying for your high end thickness gages.

The ECHO FD is mechanically designed from the ground up to offer the latest in ergonomic design. It has a convenient rubber boot with stand, 4 point chest harness, padded strap and even a finger hole for the ultimate in instrument balance. We even designed in the ability to use a magnetic pipe stand. All keys can easily be reached with your thumb and the keys are raised rubber keypad with superior tactile feedback. The “F” keys light up for alarm and charging conditions.

if field upgradeable options are enabled,  ECHO FD can even toggle from a flaw detector, corrosion or precision thickness gage making it the smallest and most affordable unit in the world to offer such a vast application set.

Grid View for ECHO Series:

The Grid View data logger allows the operator to create files and turn on the “Grid View” feature where you can see, real-time, the live A-scan at the top and the cells within the data logger file being saved below.
