A device for ultrasound tests, includes one or more transducers for generating ultrasound beams with different powers/frequencies to be projected in direction of multiple targets, to ensure separate control of the temperature both of the targets and of the transducers and allows performing several tests contemporarily, by optimizing the functionality and the efficiency of the device, and guaranteeing results comparable therebetween for each test. The device also includes: a first supporting structure having at least a closed chamber receiving the transducer bodies and is isolated from a propagation liquid medium, by leaving exposed each respective vibrating surface in contact with the liquid medium at a prefixed distance from the respective targets, the closed chamber containing a thermorefrigerating fluid in contact with the body of the transducers; a second supporting structure for the targets; means for refrigerating the transducer bodies; and means for keeping the liquid medium at a predetermined temperature.
