Ultrasonic thickness gauge
KM 131D
Introduction :
The intelligent and hand-held ultrasonic thickness gauge is controlled by a microprocessor,
which can measure thickness and sound speed of various materials quickly, accurately
and without damage by ultrasonic measurement. This instrument is capable of accurate
measurement for different materials or parts in industrial production, as well as monitoring
pipelines and pressure vessels of production equipment, and corrosion degree of various
parts in use. It can also be widely used in manufacturing, metal processing, commodity
inspection and other testing areas. Any material that allows ultrasonic to transmit at a
constant speed and that is distinguishable from waves reflected from the back side is
applicable to this instrument.
Application :
The thickness of any good conductor for ultrasonic waves with top & bottom surfaces
parallel to each other, like metal, plastic, ceramic & glass, can be measured with the
instrument. For example : aluminum, copper, gold, resin, water, glycerin, etc. The internal
particles of cast iron are too big for this instrument!
