Standard two power options to vary cleaning from gentle for delicate parts to periodic short blasts of power for hard to clean parts. 3 controls including Amplitude control to vary ultrasonic power, Duty Cycle Control to control the amount of ultrasonic energy delivered and Frequency control to adjust the frequency of the ultrasonic energy reducing audible noise from subharmonics.
