Tube probe with a measurement range from 0 – 1,500 μm. Especially developed for coating thickness measurement in bores, tubes and grooves. With this probe, coating thickness measurements on difficult-to-access areas are possible with a high measuring accuracy. The newly developed, deflecting suspension of the sensor head results in a very small measuring uncertainty and high reproducibility of measurement values. For measurements on iron/steel and non-ferrous metals. Pipe probe with a measuring range of 0-1,500 μm. Specially developed for layer thickness measurements in holes, pipes and grooves. At a depth of immersion of Ø 13 mm and 165 mm insertion length also coating thickness measurements in hard to reach places with high accuracy are possible. A very low measurement uncertainty and a high reproducibility is achieved by the resilient mounting of the sensor head. For measurements on iron and steel and non-ferrous metals.
