Century 2100 TENS Unit

The CENTURY 2100 is a three mode TENS unit with a timer. It can operate under three different modes. In Burst mode, the TENS unit produces a series of seven quick pulses followed by a rest. The cycle repeats itself twice every second. In Modulation mode, the TENS unit automatically varies the amplitude of the pulse every four seconds.

This is a dual channel unit, which allows you to use up to four electrodes at a time (two electrodes per channel). The TENS unit is portable and may be clipped to a belt, shirt pocket, bra or other clothing.
