Product Description

TT300 Ultrasonic Wall Thickness / Material Thickness Gauge

The TT300 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 good ultrasonic wave-conducting as long as the material has parallel top and bottom surfaces. With uses in many areas of industry the TT300 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. With the TT300 you can record up to 500 readings and download them to a computer.
Features:

  • Easy to use handheld thickness gauge
  • Suitable for most metallic and non-metallic materials
  • Display current thickness or minimum thickness (menu selectable)
  • Upper-lower limits setting and sound alarm
  • Memory for 500 stored values
  • Two point calibration
  • Display resolution 0.1mm/0.01mm selectable
  • Display in mm or inch
  • LCD display with adjustable backlight
  • Low battery indicato
  • RS232 output for data transfer

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.
