Thickness gauges are non-destructive measuring devices for measuring material thickness when cutting, dismantling, or damaging the piece is not possible or desirable. The measurement is usually based on ultrasonic pulse-echo technology, where a sound wave is transmitted through the material and the thickness is determined based on the reflection. This group of gauges is particularly suitable for measuring the thickness of metals, plastics, and glass, and for monitoring wear and corrosion. They are commonly used in industrial maintenance, inspection, and quality control, for example in piping, tanks, plates, and structures. Porous materials (such as concrete, wood, or Teflon) are generally not suitable for ultrasonic measurement. The range includes models with different measuring ranges and accuracies to support a variety of applications – from fast field measurements to more accurate inspection measurements. Gauges are calibrated either using the calibration block supplied or from a reference sample. A couplant is also used to ensure reliable sound transmission between the probe and the surface to be measured. Several models have: - digital display for easy reading - unit conversion (mm/inch) - automatic power cut-off - ability to change probes for various materials and temperatures - wide measuring range (typically around 1-400 mm depending on model) Typical applications: - Wall thickness measurement of pipes and tanks - Wear and corrosion monitoring - Inspection of plate and steel structures - Maintenance and repair in industry - Quality control and inspection measurements |
