Ultrasonic thickness gauges



The ExScan1000 is a precision Ultrasonic thickness gauge. Based on the same operating principles as SONAR.




ExScan1000 Intended Use


The ExScan1000 is a portable ultrasonic thickness gauge that provides accurate thickness measuring of various materials, along with the scanning of a test piece to record its minimum thickness value.
The instrument is intended for use in a wide range of industries to evaluate the wall thickness of tanks, pipes, body parts, plates, beams or support structures, as well as to monitor the condition of corroded surfaces, even with single-sided access to the test piece.
The device has an ergonomic and user-friendly design. During on-site operation, the shape and material of its case allow holding the thickness gauge firmly with one hand only.
Due to IP65 water- and dust-proof rating, as well as display backlight, the instrument can be used in extremely harsh environment.


Key Features

  • Large characters on the backlit display make reading easy even in poor light conditions.
  • The ExScan1000 can run up to 200 hours with a single battery pack.
  • Two-point calibration and automatic measurement of ultrasonic wave propagation ensure high-precision results.
  • Display backlight can be automatically turned On/Off to prolong the battery life.
  • The Sealed membrane keypad that is resistant to oil and petroleum products with six tactile-feedback keys makes the instrument operation more comfortable.
  • The ExScan 1000 kit includes a rubber shoe to protect the probe and minimize a potential impact of hand warmth on measurements.
  • The instrument is compatible with a wide range of UT probes / transducers to measure various levels of thickness and shapes of test pieces.

Basic applications

  • Thickness measurements for various materials.
  • Detection of corrosion pits.
  • Recognition of material laminations.
  • Search for thinned walls in a test piece.

Industrial sectors

  • Power generation - measurement of wall thickness in pipelines, pipe elbows, base materials (semi-products), as well as thickness of near-weld zones in pipe joints.
  • Aviation - measurement of wall thickness of aircraft steel parts and portholes (windows) with single-sided access to the test piece.
  • Metallurgy and machinery - measurement of wall thickness of slabs and strips; sample check of wall thickness of rolled plates; measurement of wall thickness of boilers, tanks, pipes.
