TT100 Low Cost Ultrasonic Wall Thickness / Material Thickness Gauge

Product Description

The TT100 Low Cost Ultrasonic Wall Thickness / Material Thickness Gauge is a hand-held microprocessor controlled thickness gauge, specifically designed for measuring the thickness of metallic and non-metallic materials eg. aluminium, titanium, plastics, ceramics, glass and other ultrasonic wave-conducting materials. It can measure thickness, as long as the material has parallel top and bottom surfaces.

The TT100 can perform precise measurements on various types of raw materials, components parts, and assembled machinery. It can also be used to monitor all types of pipes and pressure vessels for loss of thickness due to corrosion.

The TT100 is very easy to use.  After a simple calibration to a known thickness or sound velocity, the gauge will give fast and accurate readings in millimeters. Sound velocities for 5 different materials can be pre-set and 10 thickness readings can be stored in the memory.

Sound Velocities

Sound Velocities / Speed of Sound in Materials for Ultrasonic Thickness Gauges

The Ultrasonic Thickness Gauges can be programmed by the user to the appropriate Material in two ways :

  • Using known standards of the same material – set the calibration to the thickness.
  • Using the frequency calibration, set the frequency to the appropriate Material using the Velocity / Speed of Sound Chart below.
