Digital Ultra Sonic Cleaner Bath Timer Stainless Tank Cleaning 15L Ultrasonic Description: 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 enougugh to penetrate even microscopic crevices, cleaning them thoroughly and consistently. Features: 1. High working frequency increases ultrasonic activity 2. Cleaning times and temperatures controlled electrioncally. 3. As the ultrasonic working indirect heating and the heated tank will speed up the ultrasonic cleaning process. 4. The bubbles are small enougugh to penetrate even microscopic crevices, cleaning them thoroughly and consistently 5. For cleaning dirt, oil and bacterium that are difficult to peel off in metal products Specification:  Condition: 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 Package included : 1 x 15L Ultrasonic Cleaner Note: During cleaning, the"ZiZi" noise is normal.
