Wall thickness gauge SA40
Combination gauge for non-destructive ultrasonic thickness measurement
The SA40 is a small and handy ultrasonic wall thickness gauge. The smart instrument is capable of measuring the wall thickness of a great variety of metallic and nonmetallic materials e.g.: iron, steel, aluminum, brass, copper, lead, magnesium, nickel, titan, zinc, beryllium, molybdenum, quartz glass, acrylic glass, nylon, polyethylene, polystyrene, silicon and many more. The usage of different probes ensures perfect flexibility at different circumstances for instance when measurements have to be taken at hardly accessible spots or under extreme temperatures.
Through the usage of wall thickness gauges’ materials which are exposed to corrosion or erosion can be controlled and thus, their safe usage is guaranteed.
