The Sonicator 740 is a 1 MHz and 3 MHz therapeutic ultrasound unit that comes standard with a 5 cm² dual-frequency applicator and is well-built. It is lightweight and portable, and the good folks at Mettler created the Sonicator 740 with a universal applicator cable to allow for quick and easy applicator alteration. An optional rechargeable lithium-ion battery pack allows you truly to take therapy on the road with you. Large soft-touch controls provide setup for treatments that run quickly and easily, and the backlit display demonstrates all treatment parameters and conditions.
