Boasting 1 MHZ and 3 MHZ frequencies, the SONOSTAT® 135 is able to render two different impacts and a increased level of functionality and convenience for universal therapy applications. The ultrasound treatments ate rendered ergonomically thanks to the 100% watertight treatment heads, which measure 2.5 cm² or 5 cm². Built with high quality aluminum, these heads are unlike conventional aluminum heads, making them a touch skin and delivers extreme durability that does not fade. Both the sizes of treatment heads can be connected at the same time with the SONOSTAT® 135.
