The TENS 212 is an affordable two-channel TENS unit that has continuous, modulated, and burst modes. A digital display shows all treatment parameters while the unit is in use. Pulse frequency and width may be set independently.

The soft Mettler blue color is a nice change from the typical black color of today's TENS units. The blue color makes the 212 easy to see from across the room.

Transcutaneous Neuromuscular Electrical Stimulation (TENS) has proven its high value as a method of pain therapy and is a great help to the experienced clinician. With some indications, medical practitioners can prescribe a unit to patients for use at home. The TENS 212 is a dual-channel electric stimulator for active treatment application, which is equipped with a Liquid Crystal Display indicating operation modes and output as well as a microprocessor for controlling the system.

The electronics of the unit create electric impulses: the intensity, pulse duration, pulse frequency, and modulation of these impulses can be adjusted by a button or a knob.

The TENS 212 can be plugged into the Sonicator 740 using a pin to banana adapter to perform combination therapy.
