The ultrasonic cleaner is a microprocessor controlled device that uses ultrasound or high frequency sound waves to clean jewellery and other delicate items. Ultrasonic cleaning is based on the cavitation effect caused by high frequency ultrasonic wave vibration signals in liquid. Microscopic bubbles that expand and quickly collapse cause cavitation, which creates an effective cleaning effect on the surface of the object being cleaned. In addition, the bubbles are small enough to penetrate even microscopic crevices and clean them thoroughly and consistently. High efficiency saves cleaning solvents, heat energy, workplace and labour! It is the use of digital programmes in the ultrasonic cleaner to control the unit according to the amount and condition of the items to be cleaned to select a working cycle time. As a result, it is more convenient and efficient than hand washing, steam cleaning, high pressure water jet cleaning or other machines.
