The Auto*Therm 391 combines the ME 390 with an arm, inductive coil applicator, capacitive electrodes, and heavy-duty cart with ample storage space. Using this model, you will be able to choose from two different modes of application: the deep penetration of inductive coil diathermy, or the shallower capacitive style with the soft-rubber plates which are ideal for covering a large treatment area like a leg when treating the Sciatic Nerve. Continuous and pulsed modes allow you to customize treatment parameters for your patients.

The Auto*Therm 391 features a locking arm that makes it easy to position the drum on the patient. The sturdy cart allows you to roll the unit around your clinic and provides ample storage space for all of your diathermy accessories and supplies.

Diathermy treats a much larger surface area and has much deeper penetration levels than other thermal modalities. Since 1968, Mettler Electronics has produced shortwave diathermy (SWD) units that produce comforting deep heat in muscle tissues. Shortwave diathermy is used when the clinician needs to provide deep heat to a larger area than normally covered by ultrasound. Diathermy is also the only unattended modality in the country allowing the clinician to attend to other patients while the treatment is running. A patient pullcord allows the patient to stop all output if the treatment becomes uncomfortable.
