NorbarEvotorque®2
The EvoTorque®2 is an electronic torque tool designed to accurately apply torque to threaded fasteners. Tools are factory calibrated to ±3% of reading. The unique ‘intelligent joint sensing’ technology continually measures the joint during tightening and when necessary, employs dynamic braking to avoid torque over-shoot due to motor inertia. Consequently, EvoTorque®2 can apply torque accurately over a wide range of joint rates from hard (high torque rate) through to soft (low torque rate). All EvoTorque®2 tools are highly tolerant of supply voltage and frequency variation. If the supply voltage is outside of tolerance then, as a safety feature, the tool will be prevented from starting.

NorbarHandtorque® Compact Series Kits
Multiplier & Torque Wrench Kits
For convenience, it is now possible to purchase a torque multiplier from the ‘Compact Series’ packaged with the appropriate torque wrench, up to 4000 N⋅m. This allows the operator to arrive at the bolting application with everything needed in one robust carry case. Space has also been allowed in the carry case for accessories such as sockets.
