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 effective cleaning action on the surface of object being cleaned. Additionally, the bubbles are small enough to penetrate even microscopic crevices, cleaning them thoroughly and consistently. Features: High working frequency increases ultrasonic activity Cleaning times and temperatures controlled electronically. As the ultrasonic working indirect heating and the heated tank will speed up the ultrasonic cleaning process. 15L capacity Quality Guaranteed, CE / FCC / ROHS. Specifications: Ambient temperature: -10 ?? ~ 40 ?? Humidity: 35% to 85% Dimensions :( length) 355X (width) 330X (high) 280mm Within the tank size :( length) 330X (width) 300X (depth) 150mm Packing size :( length) 520X (width) 360X (depth) 350mm Cleaning tank capacity: 15.0 liters Ultrasound System: adjustable power 144W ~ 360W (6 Ge 60W transducer), frequency 40KHz Heating system: 400W digital control heating system Cleaning Time control: 1 to 30 minutes of digital control ultrasonic working time Note:Everytime when you turn on the machine ,the working time should not too long ,please pause 5 minutes to radiating after it worked about 15 minutes ,in order to better protect the machine , and reduce the failure rate. Thanks Note:The machine's heating function is just a auxiliary function,you can begin to clean your things when the temperature at 20??. You need not to added a higher temperature before cleaning. Note:The machine's tank actual capacity will be smaller than marked capacity because of the tilt tank. Hope you can understand.
