The thickness meter can measure material thicknesses up to 300 mm. So that the material thickness of a wide variety of homogeneous materials can be measured, it is possible to store the corresponding sound velocity in the thickness meter. - Measuring range: 1.20 … 300.0 mm / 0.04 … 11.81" - Accuracy: 0.5% of measured value + 0.05 mm - Memory capacity: 1500 measured values - Calibration reference on housing - High temperature probe: -10 … 350 C / 14 … 662 F
