Product Description

Introducing Stimulation3 by Mettler Electronics

With the new Trio*Stim, Mettler puts power in the palm of your hand. Now you can perform three types of therapies: Muscle Stimulation (EMS), TENS, and Microcurrent. All with one fully portable, programmable, battery-operated unit. There’s no cord to tie you down, so the possibilities are limitless. For clinicians, the total portability of the Trio*Stim makes it ideal for muscle re-education or TENS. Plus, the Trio*Stim can be used in the clinic and then sent home with the patient for continued care. Athletic trainers and home health professionals will also appreciate the powerful capabilities the Trio*Stim delivers in the field. The Trio*Stim offers new levels of treatment flexibility to anyone who prefers a hand-held, fully portable Microcurrent device. There’s nothing like the Trio*Stim anywhere. Yet this is a value-priced unit, with all the quality and expertise of Mettler built in. The Trio*Stim is small enough to fit in the palm of your hand, yet it delivers EMS, TENS and Microcurrent therapies. And that’s just the beginning. Spend a few moments operating the Trio*Stim, with its large, user friendly LCD screen, message display and four simple buttons. You’ll quickly realize that the battery-powered Trio*Stim, despite its small size and price, is packed with powerful capabilities. Two-channel stimulator allows either TENS or microcurrent stimulation to patients for pain; or muscle stimulation for patients who require a stimulator to relax muscle for use during one treatment session. Comes complete with one 9-volt battery, two lead wires, one package of 2" ValuTrode self-adhesive electrodes, belt clip and carrying case. Two-year limited warranty.
