+31 (0)35-5882450 Extreme duty torque wrenches for heavy-duty applications

E-RAD BLU-S electronic series

Torque range: 135 – 10.000 Nm

In addition to the standard E-RAD BLU, RAD also offers the E-RAD BLU-S, a transducer equipped E-RAD BLU for the highest accuracy on the market featuring torque measurement on the bolt.


This electronic torque wrench automatically adjusts and calibrates itself via a built-in transducer on your bolt connection. This system eliminates all joint sensitivity.

The E-RAD BLU-S has its transducers position on the outpoint of the gearbox and guaranties therefore that torque displayed is torque applied to the fastener.

  • Password protection on 3 user levels: basic, intermediate and advanced
  • Operator identification – Ensures traceability of each torque sequence performed
  • Capable of torque and angle bolting sequence
  • LED indicator lights (Pass/Fail) – Located on both sides, these visual signals indicate the status of torque procedure for maximum accuracy
  • Extremely low noise level – only 75 dB
  • Optional:
      • Additional torque wrenches*
      • 120V Control box
      • 6,1 and 7,6 meter control box cable
