The wall thickness meter can measure material thicknesses up to 225 mm. To ensure that the material thickness of a wide variety of homogeneous materials can be measured, it is possible to store the corresponding sonic velocity in the wall thickness meter. For materials such as steel, aluminium, zinc, silver and gold, the appropriate sonic velocities are already stored in the device library. This means that the wall thickness meter can be used universally.

Individual maximum and minimum values can be stored with the wall thickness meter's limit value function. If the measured value of the test specimen is outside the limits, the wall thickness meter signals this visually. If required, the wall thickness meter can also provide acoustic signalling in addition to the visual display. The wall thickness meter is therefore used, for example, in quality assurance and incoming goods inspection.

The wall thickness meter has a data memory on which the measured values can be recorded. After a measurement process, the stored measured values can be analysed directly on the wall thickness meter. The stored data is displayed graphically by the wall thickness meter. In addition, each individual measuring point can be approached and read in the graphic of the wall thickness meter. To simplify the analysis of the measured values, the average, the largest and smallest measured values are displayed on the wall thickness meter. The wall thickness meter can optionally be equipped with an ISO calibration certificate.
