Ultrasonic Thickness Gage – UTG-8

The UTG-8 is a portable ultrasonic thickness gage that offers accurate thickness measuring of different materials, and also scanning of the tested item in order to record its minimum thickness value.

The instrument is intended to be used in an extensive range of industries in order to evaluate the wall thickness of tanks, body parts, plates, pipes, beams or support structures, including condition monitoring of corroded surfaces, even with one-side access to the test item.

The device is available with a user-friendly and ergonomic design. The case shape and material allow for the thickness gage to be held firmly with one hand only during on-site operation.

Due to the IP65 water- and dust-proof rating, as well as the display backlight. The instrument can be used in very harsh environments.

Key Features

  • Large characters on the backlit display make reading effortless even in poor light conditions
  • UTG-8 can run up to 200 hours with a single battery pack
  • Two point calibration and automatic measurement of ultrasonic wave propagation guarantee high-precision results
  • Display backlight can be automatically turned On/Off in order to prolong the battery life
  • Sealed membrane keypad that is resistant to petroleum and oil products with six tactile-feedback keys allows the instrument operation to be more comfortable
  • Delivery set comprises of a rubber shoe for protecting the probe and minimizing a potential impact of hand warmth on measurements
  • The instrument is compatible with an extensive range of UT probes/transducers for measuring different levels of thickness and shapes of objects under test

Basic Applications

  • Detection of corrosion pits
  • Recognition of material laminations
  • Search for thinned walls in a test item
  • Thickness measurements for different materials

Industrial Sectors

  • Railway - thickness measurement of railway wheel disks during their production
  • Power generation - measurement of wall thickness in pipe elbows, base materials (semi-products), pipelines as well as thickness of near-weld zones in pipe joints
  • Aviation - measurement of wall thickness of aircraft steel parts and portholes (windows) with one-side access to the test item
  • Machinery and metallurgy - measurement of wall thickness of strips and slabs; sample check of wall thickness of rolled plates; measurement of wall thickness of tanks, pipes and boilers
  • Oil and Gas industry - measurement of wall thickness of pressurized vessels, underwater line manifolds of main gas pipelines, gas and oil tanks, above-ground pipeline branches, as well as pump and valve bodies
  • Pipe industry - measurement of pipe wall thickness; recognition of thinned spots in the pipe wall; detection of laminations in the pipe wall
