Transducer SRTT-B is the new generation of Atlas Copco stationary reaction torque transducers with improved durability, thanks to their new mechanical design. Designed for testing any kind of tools: from wrenches, click wrenches and power tool models where rotary action is not desired during measurement. Its new patented system of fixing the joint simulator on top avoids any possible errors due to the mechanical play between the two devices. A complete range of accessories and a mechanical joint simulator enables you to test shut-off tools or wrenches with square drive output.
