The new Sonicator Plus 920 is a two-channel combination unit with both a membrane panel and a touch-sensitive screen to allow clinicians to quickly set up treatments. The microprocessor-controlled Sonicator Plus 920 provides interferential (4-pole), premodulated (2-pole interferential), medium frequency (Russian), EMS, high volt, TENS, microcurrent and DC waveforms. In addition, the Sonicator Plus 920 offers 1 and 3 MHz ultrasound using a dual frequency 5.5cm² applicator. An optional dual frequency 0.9cm² applicator is also available. This product allows clinicians to use up to two different waveforms using two channels simultaneously or independently. They can choose between several different amplitude modulation options such as the surge, reciprocation and vector sweep. The interferential and premodulated waveforms offer frequency modulation as well as a static frequency options.
