Since 1972 Mettler Electronics has produced an affordable shortwave diathermy (SWD) unit that produces 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. The illustration below shows the relative penetration of various heating modalities.

Options
- Auto*Therm 390
The Auto*Therm 390 can be easily carried between treatment rooms when the soft-rubber capacitive pads are being used. It provides shortwave diathermy with either continuous or pulsed modes. - Auto*Therm 391
The Auto*Therm 390X is the same as the Auto*Therm 390 but comes with optional cart to provide a solid platform for the inductive coil drum electrode. Like the 390, it provides shortwave diathermy with either continuous or pulsed modes. - Auto*Therm 395
he Auto*Therm 395 features continuous and pulsed shortwave diathermy. This advanced, automatic tuning unit has no less than eight different treatment applicators: three inductive coil applicators, three spaced condenser sets and two soft, flexible plate electrodes. High performance, multi-jointed arms lock in place for ease of use and safety. A membrane panel and intensity control knob make treatment set-ups quick and easy.
