Tohnichi TT2000 Tension Meter

Made in Japan
Manufacturer: Tohnichi
Model: TT2000

Ultrasonic tension meter that can perform non-destructive tests to determine bolt axial tension changes that may occur over time. Please note that the TT2000M has been discontinued.

TT2000
You can connect to a personal computer and conduct data management and analysis. We also create software that meets customer requirements (only for TT2000C). Feel free to contact us about this.

Application

  • Bolt tension test.
  • Bolt aging test, loosening test.
  • To define the optimum torque level for the bolt.

Features

  • Japanese-language display on large, easy-to-read color screen.
  • Simple operation using dialogue-style data input method.
  • Compact and light weight. Portable for use at the work site.
  • Portable battery available as option.
  • Variety of functions, overlapping of wave pattern and wave detection change are available for measurements with high reliability.
  • Simplified bolt dimension will be displayed in graphic with input values expressed in red.
  • Bi-directional communication with PC for data creation, and measured value backup. (* Note: Except TT2000)
  • We also supply a special English text display model.
  • Can also be used at development and manufacturing sites outside Japan.
