Tohnichi CTB2-G Digital Retightening Torque Wrench

Capacity 10 / 20 / 50 / 100 / 200 / 360 / 500 / 850 Nm

For Re-Tightening Inspection of Tightened Bolts

The CTB2-G is suitable for quality inspection using the retightening torque test method. It detects the original tightened torque applied on the bolt by re-tightening inspection.

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.

Table is showing the torque ranges specified by manufacturer. Usage in the medium range (approx. 1/3 to 4/5 of rated capacity) is recommended. If you would mainly work close to the load capacity limit, in general a larger tool may be more recommendable.
