NorTronic 1/2" Square Drive, 50 N·m, 868MHz

NorTronic Model 50

In order to communicate wirelessly between a NorTronic and a PC it is necessary to purchase the appropriate USB Wireless Adaptor. This is sold separately because each adaptor can handle up to eight NorTronic wrenches.

There are two communication frequency versions of the NorTronic because different countries operate different licence free radio transmission bands. The two frequencies that we offer cover most areas of the world. Please click here to view the map we have provided as a guide to the appropriate frequency to buy however, it is the user’s responsibility to ensure that local laws are complied with.

FAQ

Use Our Calculators

Norbar has devised easy-to-use online calculators that support the correct application of torque in three key areas:

  1. Unit conversion to assist international measurement definitions.
  2. Torque extension for setting correct values
  3. Torque tension to identify precise levels of torque to be applied for individual applications.
