Ultrasonic Thickness Gauge
model Elcometer 204



The Elcometer 204 Steel Ultrasonic Thickness gauge is a handheld gauge providing fast and accurate measurements of the thickness of steel. The principal advantage of ultrasonic measurement over traditional methods is that ultrasonic measurements can be performed with access to only one side of the material being measured. The Elcometer 204 is pre-calibrated for ease of use and the gauge can be “zeroed” to ensure accuracy. It is capable of measuring the thickness of material such as steel plate with repeatable accuracy. Battery powered, the Elcometer 204 features an easy read backlit screen making it ideal for use in low light areas. Supplied with everything required to start measuring as soon as the gauge is received, the Elcometer 204 provides an ideal, low cost solution for measuring thickness of steel.

  • Low cost and easy to use:
    Provided with everything required to use straight from the box.
  • Ready to use:
    Supplied complete with transducer and gel – ready to use straight from the box.
  • Probe Zero:
    “Zeroing” the gauge ensures correct measurements.

Material Thickness

The thickness of materials cannot always be determined by direct measurement as access to both sides is not always possible.The effects of corrosion and erosion at the back of a metal panel may reduce its thickness significantly yet not affect the front surface. Pipelines, for example, may appear corrosion free on the outside but can be eroded by the flow of material on the inside. Machined or cast items may have thin walls that cannot be determined by callipers or other non-destructive tests.
