Transfer Torque Wrench- TTW-101

Transfer Torque Wrench-101 is a form of Torque Wrench which consists of a torque transducer with a lever and interchangeable adopters connected to an amplifier/indicator or Sushma Display Unit through a cable.

It is a key device in the establishment of a traceability of SI units in toque calibration. TTW, by virtue of their design, enable the torque to be introduced via lever arm (similar to construction of click type torque wrench).

Transfer Torque Wrench-101 are usually insensitive to bending moments and to transverse forces, leading to lowest contribution to required measurement uncertainty.



  • Capacity options from 5 Nm to 3000 Nm with male square drive output
  • Accuracy class 0.2 according to DKD -R 3-7-2010
  • Extremely insensitive to lateral, axial forces and to bending moment
  • Calibrated at ISO 17025 accredited laboratory by using Dead weight calibration machine as per DKD-R 3-7-2010 for measurement traceability.
  • Calibrated in clock-wise mode (CCW optional)
  • Insensitive to changes in the lever arm length of the wrench.
  • Can be mounted in any orientation-horizontal, vertical or otherwise.
  • To be used in conjunction with Sushma high precision digital display unit having 200,000 counts.
  • Also, compatible with any mV/V input strain gauge measuring amplifier.
  • Can be used at both permanent and onsite facility
