The ETT series is a line of torsion testing machines engineered by Wance. It is suitable for use in loading and weighing in both rotational direction.
The machine can determine the torque load of a specimen, as well as its behavior under conditions of continuous or steady torque loading, in both directions. It is equipped with a variable speed drive loading system, digital control and indicator in a fixed unit.
The unit features a strain gage torque sensor with a weighing head mounted on a movable unit, which allows placing on rails for accommodation of changing lengths of specimens.
