Ultrasonic Performance Meter provides a fast, effective and simple to use the method of measuring the ultrasonic activity generated in ultrasonic baths. The sonicator work on the principle of physics wherein the high-frequency electrical energy is transformed into ultrasonic waves using transducers. This high energy wave creates minute vacuum bubbles which rapidly expand and collapse. This process is known as Cavitation which helps in breaking or mixing of the sample such as cells, solutions etc. The ultrasonic activity meter is used to give a comparative measurement of one baths performance over a period of time.
