Graham Field

T.E.N.S. (Transcutaneous Electrical Nerve Stimulation) is indicated under a physician's prescription for the symptomatic relief and management of chronic (long-term) pain and the treatment of post-operative or post-traumatic pain. 

  • Dual channels
  • Three modes: Standard, Burst, Modulation
  • Molded carrying case, including: instructions, accessories (four electrodes and lead wires), and 9V battery.

* Federal Law (USA) restricts this device to sale by or on the order of a physician.

Channels: Dual
Pulse Amplitude: Adjustable, 80 mA peak maximum for positive pulse or -20 mA peak maximum for negative pulse into 500 ohm load each channel.
Pulse Rate: (Adjustable) 2 Hz – 120 Hz
Pulse Width: (Adjustable) 40 µ S – 260 µ S
Modulation Mode: Pulse width is automatically varied in a cyclic pattern over an interval of nominally 5.0 seconds maximum. Pulse width decreases linearly over a period of 1.5 seconds from the control setting value to a value which is decreased 45% maximum. The narrower pulse width will continue for 2 seconds maximum, then increase linearly over a 1.5 second period to its original value. The cycle is then repeated.
Burst Mode: Bursts consist of 9 ±2 pulses at maximum pulse rate.
Bursts occur twice every second.
Wave Form: Asymmetrical Bi-Phasic square pulse.
Max. Charge per pulse: 21 micro coulombs maximum. Positive pulse and negative pulse separate.
Battery: 9 volt battery (alkaline, or nickel-cadmium rechargeable).
Size: 23 x 64 x 91mm
Weight: 130 grams (battery included)
