CTB2/CTB2-G

Digital Retightening Wrench

Inspections

Digital

Interchangeable Head

Direct Reading

Light indicator/buzzer

Re-chargeable

Detects the original tightened torque applied on the bolt by re-tightening inspection.

CTB100N2X15D-G [L'=384 mm]

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 own new re-tightening torque measurement algorithm (T-point method).
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.
DtRcv (Data Receiver) is a wired data input tool facilitating Excel® data management, and can be downloaded without charge. * ExRcv (Excel Receiver) was upgraded to DtRcv (Data Receiver) in March 2021. * Excel® is a registered trademark of Microsoft Corporation.
