The ultrasonic wall thickness gauges can measure material thicknesses up to 300 mm / 11.81". So that the material thickness of a wide variety of homogeneous materials can be measured, it is possible to store the corresponding speed of sound in the thickness gauge. For materials such as steel, aluminum, zinc, silver and gold, the appropriate sound speeds are already stored in the device library. This means that the thickness gauge can be used universally.

With the limit value function in the ultrasonic wall thickness gauges, individual maximum and minimum values ​​can be stored. If the measured value of the test piece is outside the limits, the thickness gauge signals this visually. If necessary, the signaling can also be done acoustically by the thickness meter in addition to the visual display. This is why the thickness gauge is used, for example, in quality assurance and in incoming goods inspections.

The ultrasonic wall thickness gauges has a data memory on which the measured values ​​can be recorded. After a measurement sequence, the stored measurement values ​​can be analyzed directly on the thickness gauge. The stored data are graphically displayed by the thickness gauge. In addition, each individual measuring point can be approached and read in the graphics of the thickness gauge. For a simplified analysis of the measured values, the average, the largest and smallest measured value is displayed on the thickness gauge.
