Introduction

USN 52R/USN 52L

1.3 USN 52R/USN 52L

USN 52R/USN 52L are lightweight, compact ultrasonic flaw detectors which is especially well suited for

•locating and evaluating material flaws,

•measuring wall thicknesses.

•documenting all test results and readings.

USN 52R:

•high-resolution EL display, 146 mm x 67 mm (5.75“ x 2.65“), 552 x 256 pixels

USN 52L:

•transflective LCD screen, 114 mm x 75 mm (4.5“ x 3.0“), 480 x 320 pixels

Special features of the two versions:

•lightness in weight (2.7 kg including batteries) and small in size,

•an easy-to-clean keypad,
