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.
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.

Notes:
1. Optional thermometer can be connected to TT2000C for automatic temperature adjustments.
Input temperature range is from -40℃ to 200℃.
Measurement over 60℃ requires a sensor specially designed for high temperature.
2. RS232C communication is possible only with TT2000C.
3. 12V DC power can be used only when using the optional portable battery.
