Trigno Goniometer Adapter

Accurately measure joint angles

The adapter is compatible with several industry-standard twin axis devices. Simply connect the goniometer to the adapter, turn on, and begin streaming synchronized angle data to EMGworks®. The adapter supports three gain settings (low, medium and high) which can be easily selected in our software to maximize the dynamic range for the specific goniometer being used. A simple calibration in EMGworks® will yield highly accurate measurements in two orthogonal planes.
