The USN 58R Portable Flaw Detector -,New EL display, more performance, easier to use, and it loves the cold.

The new USN 58R, introduced to the North American market in October 2001, incorporates the most requested features in the easiest-to-use instrument available.  The USN 58R with hi-brite EL display, 60 Hz update rate, and "single shot" measurement technique produce a fast, smooth response for critical field testing. A new reverse video mode and wide viewing angle provide improved viewing outdoors and operation in lower temperature environments.

Fast "spin & set" operation using two rotary knobs, trigonometric flaw location calculations with curvature correction, and a new AWS D1.1 weld rating calculation make it an ideal instrument for portable weld inspection. A 480" measurement range in steel, .25 to 25 Mhz frequency capability, two independent flaw gates, 2K (PRF) pulse repetition frequency, and real-time analog and TTL outputs provide maximum versatility to satisfy a wide range of testing applications. The exclusive SmartView feature displays the most important information (relevant shot) for critical scanning and rotating part inspections. Full 8 hours of use with "on-board" rechargeable lithium Ion battery pack.

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 immersion systems work, the USN 58R can handle your testing requirements and keep on handling them.
