Are beam torque wrenches accurate?

Are beam torque wrenches accurate?

These wrenches are accurate both for both left and right hand torque, and there is no chance that the beam will fatigue and lead to inaccurate readings.

How does a deflecting beam torque wrench work?

The load carrying beam is straight and runs from head to handle, it deflects when torque is applied. The other beam (indicating beam) runs directly above the deflecting beam for about half of the length then bends away to the side at an angle from the deflecting beam.
