CTB850N2X32D-G [L'=1387 mm]

Also compatible with custom-modified Bluetooth®-equipped CEM3-BT / CEM3-G-BT.

Application

  • For quality inspection using the retightening torque test method.

Features

  • For re-tightening inspection of tightened bolts.
  • Uses Tohnichi’s indigenous new re-tightening torque measurement algorithm (T-point method). (*Patent pending)
  • Detection sensors and software provide a final torque value that is very close to the original applied torque.
  • Internal memory saves up to 999 readings, which can be downloaded via RS232C.
  • Interchangeable head allows for use in a variety of applications.
  • Applicable for international use including the EU region.
  • Tohnichi’s interchangeable head torque wrenches can be used with our interchange head lineup which offers the best selection in the world, making these wrenches ideal for your work.
  • The CTB2-BT / CTB2-G-BT, which can send data via Bluetooth (R), can be custom-modified when ordered. *Bluetooth (R) is the registered trademark of Bluetooth SIG, Inc.
  • Using the "TDMS / TDMSHT" (Ver. 2.00) that go on sale in March 2017, the CTB2-BT / CTB2-G-BT can build a system for managing tightening data.
  • Excel Receiver software is a data input tool for Excel® data management. It can be downloaded for free. * Note: Excel® is a registered trademark of the Microsoft Corporation.
