Descriptions:The ultrasonic cleaner is a microprocessor-controlled device that uses ultrasonic or high frequency sound waves to clean jewelry and other delicate items. Ultrasonic cleaning is based on the cavitation effect caused by high frequency ultrasonic wave vibration signals in fluid. Microscopic bubbles that expand and rapidly collapse cause cavitation, which creates an effectivecleaning action on the surface of object being cleaned. Additionally, the bubbles are small enough to penetrate even microscopic crevices, cleaning them thoroughly and consistently. Application:Service line, Electron line, Medicament line, Laboratory, Machine line, Horniness alloy line, Chemistry line .Industry and mining enterprise, universities, colleges and institutes scientific research unit laboratory; Hospital;Electronic workshop assembly line; Clock and watch eyeglasses shop,jewelry; Jeweler's shop, Family.you will use ultrasonic cleaner for everywhere.Clean things:Electronic products, mechanical hardware fitting,eyeglasses, jewelry, clock and watch, money, fruit and so on.
