Teravan Analog TENS Electrotherapy Unit For Straightforward Control of Device Settings
The system includes a device, lead wires, four self-adhesive reusable electrodes, a 9 Volt alkaline battery, hard plastic carrying case, an instruction manual as well as eight bonus 2"x2" electrodes.
Dual isolated channels and analog controls allow for easy setting of program variables. Pulse Width 50-300us, Pulse Rate 2-150Hz, Pulse Ramp 1-8 Seconds, Pulse Amplitude 100mA peak, Timer 1-60 Minutes or Continuous, Waveform Asymmetrical Bi-Phase Square Pulse.
The pulse rate is automatically varied in a cyclic pattern over an interval of nominally 10 seconds (in max 150 Hz). Pulse rate decreases linearly over a period of 4 seconds from the control set to a value that is 40% less. The lower pulse rate will continue for 1 second, then increase linearly over a 4 second period to its original value. The original pulse rate will continue for 1 second and then the cycle is repeated. Size is 95mm high x 65mm wide x 23.5mm deep and weighs approximately 115 grams with the battery included.
