TD-50 EMG/NCVThe TECA TD 50 EMG NCV is a single channel Electromyograph capable of acquiring and displaying Electromyographic (EMG) and Nerve Conduction Velocity (NCV) data to perform routine electrophysiological studies. The instrument has an integral constant voltage electrical stimulator to provide stimuli during NCV tests. Acquired data may be analyzed using the two on screen cursors; automatic marking and measurement of Motor and Sensory NCV responses is
