Our CHECK-LINE TI-25M is designed to measure accurately the thickness of walls and the extent of corrosion of metals, ceramics, glass and the most rigid plastics from only one side!
You can use the TI-25M in different modes, either in a Single Thickness Reading mode or in a Scan mode. In the Scan mode, the probe has to be dragged over a large measuring area. Finally the minimum thickness reading measured during the “Scan” process will be displayed.
Due to its perfect design, the TI-25M probe is waterproof and can be submerged in water. Additionally, our gauge is impact-resistant, environmentally sealed and provides therefore an operation without any trouble even under tough field conditions.
