Accuracy +/- 0.25% of full scale.
Various models that range 2.5 lbf.in to 500 lbf.ft.
Bi-directional.
Compact and robust housing.
Converts any ratchet wrench into a torque sensor.
Ideal for applications with limited space accessibility.
Features ARC II technology, an instant auto-recognition system of the SMX connected to the LTT or PTT.


Connect the SMX to the square drive of a wrench and monitor the torque applied.
