Reliable torque reference transducer

Transducer SRTT-B

The Atlas Copco SRTT-B is the latest generation of stationary reaction torque transducers, redesigned with a new mechanical architecture that significantly improves durability for sustained calibration use. Suitable for testing any tool type where rotary action is not desired during measurement -- wrenches, click wrenches, and power tools in static mode -- the SRTT-B features a patented joint simulator fixing system that eliminates mechanical play errors. A complete accessories range and mechanical joint simulator enable testing of shut-off tools and wrenches with square drive output.

  • New mechanical design for significantly improved calibration durability
  • Tests wrenches, click wrenches, and power tools in static measurement mode
  • Patented joint simulator fixing eliminates mechanical play measurement errors
