TENS Unit are primarily used for managing chronic pain. Works by blocking the pain signal, and by increasing endorphins in the body. Can be worn all day or on an as needed basis. Device features include adjustable pulse rate, pulse width, and amplitude (intensity). Placement of electrodes are usually at pain site or along the nerve channels, called dermatomes.

Key features:

• Highly portable TENS Unit can be used anywhere.

• Dual, isolated channels with asymmetrical biphasic output, adjustable pulse amplitude and pulse rate.

• Three-mode operation: conventional, burst or modulation.

• Includes: caps over buttons, hard plastic case, 9-volt battery, lead wires, 4 electrodes (one pack) and manual.

• Five Year Warranty - Satisfaction Guaranteed

• Technical Specifications Channels: Dual, isolated between channels.

• Wave Form: Modified square wave with zero net (DC) component.

• Pulse Amplitude: 0 to 80mA each channel, adjustable (500 ohm load)

• Pulse Frequency: 2 to 150 Hz, adjustable.

• Pulse Width: 60 to 250 microseconds, adjustable.

• Modulation Mode: Pulse width is automatically varied in a cyclic pattern over an interval of nominally 4.0 seconds.

• Burst Mode: 7 pulses per burst, 2 bursts per second, 100Hz internal frequency of burst.

• Maximum Voltage: 100 volts, open circuit. Maximum Charge: 16 Microcoulombs per pulse.

• Power Source: 9 volt alkaline or rechargeable battery.

• Battery Life: 70 hours average usage (alkaline)

• Size: 24 x 64 x 95mm

• Weight: 130 grams (including battery)


TENS technology is normally more powerful than EMS technology. It's a stronger, deeper penetration to the muscle allowing for a more intense contraction. TENS machines stimulate sensory nerves, block pain signals, and stimulate endorphin production. Other common uses for TENS devices include acute and chronic pain, arthritis, shoulder syndromes, and other painful conditions.
