The light and compact ultrasonic wall thickness gauge SONOWALL 60 uses multi-echo technology in order to enable reliable and precise measurement through painted surfaces and surfaces with protective coatings. Simple calibration allows the use of the device with most materials. The wall thickness gauge is simple to operate and has been specifically designed for the measurement of wall thicknesses of metal components. The SONOWALL 60 can be used for the reliable measurement of pipes, tanks, pressurised containers, machinery components and steel parts. A zero-point adjustment is not necessary. The robust, waterproof device can also be used for the quick, precise and reliable measurement of rough and uneven surfaces.
