MyoTrac EMG Biofeedback

Features

• Single channel analog surface EMG biofeedback monitor
• Three sensitivity ranges to strengthen, relax, or rehabilitate
• Advanced Myoscan sensor provides unmatched input impedance and artifact rejection levels
• Electronics in the sensor pre-amplify muscle signals—eliminating “noise”
• 13-segment LED bargraph offers precise visual feedback
• Narrow and wide bandpass filters eliminate EKG interference and permit precise monitoring of normal and fatiguing muscles
• Five way tone feedback includes Proportional, Threshold, and 3 second delayed Alarm
• Volume adjusted through an internal speaker or an earphone
• Above and below threshold options signal EMG activity that exceeds or falls below threshold
• DC output connects accessories and permits computer monitoring
• Lower current consumption doubles the battery life
• 1-year warranty
• Comes with Myoscan sensor, 1 starter pkg of 3 each 2.25” round Triode™ tri-snap disposable EMG electrodes, earphone, 1 each 9V alkaline battery, carrying case, and comprehensive instruction manual
